The output point is also the location - in the text of the next character that will be read (directly - from the text in the window, not from an intervening buffer) by - a program.

After the read, as described above, the output point - will be at the beginning of the next line of text. In normal circumstances, - therefore, typed text is delivered to programs a line at a time. - Changes made by typing or editing before the text is read will - not be seen by the program reading it.

The ESC character - toggles hold mode. Some programs automatically turn on hold mode - to simplify the editing of multi-line text; type ESC when done - to allow <i>mail</i> to read the text. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - An EOT character (control-D) behaves exactly like newline except - that it is not delivered to a program when read. Thus on an empty - line an EOT serves to deliver an end-of-file indication: the read - will return zero characters. The BS character (control-H) erases - the character before the selected text. The ETB character - (control-W) erases any nonalphanumeric characters, then the alphanumeric - word just before the selected text. ‘Alphanumeric’ here means - non-blanks and non-punctuation. The NAK character (control-U) - erases the text after the output point, and not yet read by a - program, but not more than one line. All these - characters are typed on the keyboard and hence replace the selected - text; for example, typing a BS with a word selected places the - word in the snarf buffer, removes it from the screen, and erases - the character before the word. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - An ACK character (control-F) or Insert character triggers file - name completion for the preceding string (see <a href="../man3/complete.html"><i>complete</i>(3)</a>). - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Text may be moved vertically within the window. A scroll bar on - the left of the window shows in its clear portion what fragment - of the total output text is visible on the screen, and in its - gray part what is above or below view; it measures characters, - not lines. Mousing inside the scroll bar moves text: clicking - button 1 - with the mouse pointing inside the scroll bar brings the line - at the top of the window to the cursor’s vertical location; button - 3 takes the line at the cursor to the top of the window; button - 2, treating the scroll bar as a ruler, jumps to the indicated - portion of the stored text. Holding a button pressed in the scroll - bar will - cause the text to scroll continuously until the button is released. - - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Typing down-arrow scrolls forward one third of a window, and up-arrow - scrolls back. Typing page-down scrolls forward two thirds of a - window, and page-up scrolls back. Typing Home scrolls to the top - of the window; typing End scrolls to the end. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The DEL character sends an <tt><font size=+1>interrupt</font></tt> note to all processes in - the window’s process group. Unlike the other characters, the DEL - and arrow keys do not affect the selected text. The left (right) - arrow key moves the selection to one character before (after) - the current selection. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>9term</i> relies on the kernel’s terminal processing to handle EOT - and DEL, so the terminal must be set up with EOT as the “eof” - character and DEL as the “intr” character. <i>9term</i> runs <a href="../man1/stty.html"><i>stty</i>(1)</a> - to establish this when the terminal is created. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Normally, written output to a window blocks when the text reaches - the end of the screen and the terminal buffer fills; a button - 2 menu item toggles scrolling. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>9term</i> changes behavior according to the terminal settings of the - running programs. Most programs run with echo enabled. In this - mode, <i>9term</i> displays and allows editing of the input. Some programs, - typically those reading passwords, run with echo disabled. In - this mode, <i>9term</i> passes keystrokes through directly, - without echoing them or buffering until a newline character. These - heuristics work well in many cases, but there are a few common - ones where they fall short. First, programs using the GNU readline - library typically disable terminal echo and perform echoing themselves. - The most common example is the shell - <a href="../man1/bash.html"><i>bash</i>(1)</a>. Disabling the use of readline with “<tt><font size=+1>set +o emacs</font></tt>” [<i>sic</i>] - usually restores the desired behavior. Second, remote terminal - programs such as <a href="../man1/ssh.html"><i>ssh</i>(1)</a> typically run with echo disabled, relying - on the remote system to echo characters as desired. Plan 9’s <i>ssh</i> - has a <tt><font size=+1>−C</font></tt> flag to disable this, leaving the terminal in - “cooked” mode. For similar situations on Unix, <i>9term</i>’s button - 2 menu has an entry to toggle the forced use of cooked mode, despite - the terminal settings. In such cases, it is useful to run “<tt><font size=+1>stty - −echo</font></tt>” on the remote system to avoid seeing your input twice. - - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Editing operations are selected from a menu on button 2. The <tt><font size=+1>cut</font></tt> - operation deletes the selected text from the screen and puts it - in the snarf buffer; <tt><font size=+1>snarf</font></tt> copies the selected text to the buffer - without deleting it; <tt><font size=+1>paste</font></tt> replaces the selected text with the - contents of the buffer; and <tt><font size=+1>send</font></tt> copies the snarf buffer to - just after the output point, adding a final newline if missing. - <tt><font size=+1>Paste</font></tt> will sometimes and <tt><font size=+1>send</font></tt> will always place text after the - output point; the text so placed will behave exactly as described - above. Therefore when pasting text containing newlines after the - output point, it may be prudent to turn on hold mode first. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The <tt><font size=+1>plumb</font></tt> menu item sends the contents of the selection (not the - snarf buffer) to the <i>plumber</i> (see <a href="../man1/plumb.html"><i>plumb</i>(1)</a>). If the selection - is empty, it sends the white-space-delimited text containing the - selection (typing cursor).

The body typically contains an image of a file, as in <a href="../man1/sam.html"><i>sam</i>(1)</a>, - or the output of a program, as in an <a href="../man1/rio.html"><i>rio</i>(1)</a> window. The tag contains - a number of blank-separated words, followed by a vertical bar - character, followed by anything. The first word is the - name of the window, typically the name of the associated file - or directory, and the other words are commands available in that - window. Any text may be added after the bar; examples are strings - to search for or commands to execute in that window. Changes to - the text left of the bar will be ignored, unless the result is - to change the name of the window. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - If a window holds a directory, the name (first word of the tag) - will end with a slash.<br> - <p><font size=+1><b>Scrolling </b></font><br> - Each window has a scroll bar to the left of the body. The scroll - bar behaves much as in <a href="../man1/sam.html"><i>sam</i>(1)</a> or <a href="../man1/rio.html"><i>rio</i>(1)</a> except that scrolling - occurs when the button is pressed, rather than released, and continues - as long as the mouse button is held down in the scroll bar. For - example, to scroll slowly through a file, hold button 3 - down near the top of the scroll bar. Moving the mouse down the - scroll bar speeds up the rate of scrolling. (The experimental - option <tt><font size=+1>−r</font></tt> reverses the scrolling behavior of buttons 1 and 3, - to behave more like <a href="../man1/xterm.html"><i>xterm</i>(1)</a>.)<br> - <p><font size=+1><b>Layout </b></font><br> - <i>Acme</i> windows are arranged in columns. By default, it creates two - columns when starting; this can be overridden with the <tt><font size=+1>−c</font></tt> option. - Placement is automatic but may be adjusted using the <i>layout box</i> - in the upper left corner of each window and column. Pressing and - holding any mouse button in the box drags the - associated window or column. For windows, just clicking in the - layout box grows the window in place: button 1 grows it a little, - button 2 grows it as much as it can, still leaving all other tags - in that column visible, and button 3 takes over the column completely, - temporarily hiding other windows in the column. (They - will return <i>en masse</i> if any of them needs attention.) The layout - box in a window is normally white; when it is black in the center, - it records that the file is ‘dirty’: <i>acme</i> believes it is modified - from its original contents. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Tags exist at the top of each column and across the whole display. - <i>Acme</i> pre-loads them with useful commands. Also, the tag across - the top maintains a list of executing long-running commands.<br> - <p><font size=+1><b>Typing </b></font><br> - The behavior of typed text is similar to that in <a href="../man1/rio.html"><i>rio</i>(1)</a> except - that the characters are delivered to the tag or body under the - mouse; there is no ‘click to type’. (The experimental option <tt><font size=+1>−b</font></tt> - causes typing to go to the most recently clicked-at or made window.) - The usual backspacing conventions apply. As in <a href="../man1/sam.html"><i>sam</i>(1)</a> but not - <i>rio</i>, the ESC key selects the text typed since the last mouse action, - a feature particularly useful when executing commands. A side - effect is that typing ESC with text already selected is identical - to a <tt><font size=+1>Cut</font></tt> command (<i>q.v.</i>). - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Most text, including the names of windows, may be edited uniformly. - The only exception is that the command names to the left of the - bar in a tag are maintained automatically; changes to them are - repaired by <i>acme</i>.<br> - <p><font size=+1><b>Directory context </b></font><br> - Each window’s tag names a directory: explicitly if the window - holds a directory; implicitly if it holds a regular file (e.g. - the directory <tt><font size=+1>/adm</font></tt> if the window holds <tt><font size=+1>/adm/users</font></tt>). This directory - provides a <i>context</i> for interpreting file names in that window. - For example, the string <tt><font size=+1>users</font></tt> in a window labeled <tt><font size=+1>/adm/</font></tt> or - <tt><font size=+1>/adm/keys</font></tt> will be interpreted as the file name <tt><font size=+1>/adm/users</font></tt>. The - directory is defined purely textually, so it can be a non-existent - directory or a real directory associated with a non-existent file - (e.g. <tt><font size=+1>/adm/not−a−file</font></tt>). File names beginning with a slash are - assumed to be absolute file names. - <p><font size=+1><b>Errors </b></font><br> - Windows whose names begin with <tt><font size=+1>−</font></tt> or <tt><font size=+1>+</font></tt> conventionally hold diagnostics - and other data not directly associated with files. A window labeled - <tt><font size=+1>+Errors</font></tt> receives all diagnostics produced by <i>acme</i> itself. Diagnostics - from commands run by <i>acme</i> appear in a window named <i>directory</i><tt><font size=+1>/+Errors</font></tt> - where <i>directory</i> is - identified by the context of the command. These error windows - are created when needed.<br> - <p><font size=+1><b>Mouse button 1 </b></font><br> - Mouse button 1 selects text just as in <a href="../man1/sam.html"><i>sam</i>(1)</a> or <a href="../man1/rio.html"><i>rio</i>(1)</a><i>,</i> including - the usual double-clicking conventions.<br> - <p><font size=+1><b>Mouse button 2 </b></font><br> - By an action similar to selecting text with button 1, button 2 - indicates text to execute as a command. If the indicated text - has multiple white-space-separated words, the first is the command - name and the second and subsequent are its arguments. If button - 2 is ‘clicked’--indicates a null string--<i>acme expands</i> the - indicated text to find a command to run: if the click is within - button-1-selected text, <i>acme</i> takes that selection as the command; - otherwise it takes the largest string of valid file name characters - containing the click. Valid file name characters are alphanumerics - and <tt><font size=+1>_ . − + /</font></tt>. This behavior is similar to double-clicking - with button 1 but, because a null command is meaningless, only - a single click is required. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Some commands, all by convention starting with a capital letter, - are <i>built-ins</i> that are executed directly by <i>acme</i>:<br> - <tt><font size=+1>Cut</font></tt> Delete most recently selected text and place in snarf buffer.<br> - <tt><font size=+1>Del</font></tt> Delete window.

The environment of such commands contains - the variable <tt><font size=+1>$%</font></tt> with value set to the filename of the window in - which the command is run, and <tt><font size=+1>$winid</font></tt> set to the window’s id number - (see <a href="../man4/acme.html"><i>acme</i>(4)</a>).<br> - <p><font size=+1><b>Mouse button 3 </b></font><br> - Pointing at text with button 3 instructs <i>acme</i> to locate or acquire - the file, string, etc. described by the indicated text and its - context. This description follows the actions taken when button - 3 is released after sweeping out some text. In the description, - <i>text</i> refers to the text of the original sweep or, if it was null, - the - result of applying the same expansion rules that apply to button - 2 actions. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - If the text names an existing window, <i>acme</i> moves the mouse cursor - to the selected text in the body of that window. If the text names - an existing file with no associated window, <i>acme</i> loads the file - into a new window and moves the mouse there. If the text is a - file name contained in angle brackets, <i>acme</i> loads the - indicated include file from the directory appropriate to the suffix - of the file name of the window holding the text. (The <tt><font size=+1>Incl</font></tt> command - adds directories to the standard list.) - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - If the text begins with a colon, it is taken to be an address, - in the style of <a href="../man1/sam.html"><i>sam</i>(1)</a>, within the body of the window containing - the text. The address is evaluated, the resulting text highlighted, - and the mouse moved to it. Thus, in <i>acme</i>, one must type <tt><font size=+1>:/regexp</font></tt> - or <tt><font size=+1>:127</font></tt> not just <tt><font size=+1>/regexp</font></tt> or <tt><font size=+1>127</font></tt>. (There is an easier - way to locate literal text; see below.) - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - If the text is a file name followed by a colon and an address, - <i>acme</i> loads the file and evaluates the address. For example, clicking - button 3 anywhere in the text <tt><font size=+1>file.c:27</font></tt> will open <tt><font size=+1>file.c</font></tt>, select - line 27, and put the mouse at the beginning of the line. The rules - about Error files, directories, and so on all combine - to make this an efficient way to investigate errors from compilers, - etc. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - If the text is not an address or file, it is taken to be literal - text, which is then searched for in the body of the window in - which button 3 was clicked. If a match is found, it is selected - and the mouse is moved there. Thus, to search for occurrences - of a word in a file, just click button 3 on the word. Because - of the rule of - using the selection as the button 3 action, subsequent clicks - will find subsequent occurrences without moving the mouse. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - In all these actions, the mouse motion is not done if the text - is a null string within a non-null selected string in the tag, - so that (for example) complex regular expressions may be selected - and applied repeatedly to the body by just clicking button 3 over - them.<br> - <p><font size=+1><b>Chords of mouse buttons </b></font><br> - Several operations are bound to multiple-button actions. After - selecting text, with button 1 still down, pressing button 2 executes - <tt><font size=+1>Cut</font></tt> and button 3 executes <tt><font size=+1>Paste</font></tt>. After clicking one button, the - other undoes the first; thus (while holding down button 1) 2 followed - by 3 is a <tt><font size=+1>Snarf</font></tt> that leaves the file undirtied; 3 - followed by 2 is a no-op. These actions also apply to text selected - by double-clicking because the double-click expansion is made - when the second click starts, not when it ends. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Commands may be given extra arguments by a mouse chord with buttons - 2 and 1. While holding down button 2 on text to be executed as - a command, clicking button 1 appends the text last pointed to - by button 1 as a distinct final argument. For example, to search - for literal <tt><font size=+1>text</font></tt> one may execute <tt><font size=+1>Look text</font></tt> with - button 2 or instead point at <tt><font size=+1>text</font></tt> with button 1 in any window, - release button 1, then execute <tt><font size=+1>Look</font></tt>, clicking button 1 while 2 - is held down. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - When an external command (e.g. <a href="../man1/echo.html"><i>echo</i>(1)</a>) is executed this way, - the extra argument is passed as expected and an environment variable - <tt><font size=+1>$acmeaddr</font></tt> is created that holds, in the form interpreted by button - 3, the fully-qualified address of the extra argument.<br> - <p><font size=+1><b>Support programs </b></font><br> - <i>Win</i> creates a new <i>acme</i> window and runs a <i>command</i> (default <tt><font size=+1>$SHELL</font></tt>) - in it, turning the window into something analogous to an <a href="../man1/rio.html"><i>rio</i>(1)</a> - window.

If it is desired to use one of the regular - expression metacharacters as an ordinary character, that - character may be preceded by ‘<tt><font size=+1>\</font></tt>’. This also applies to the character - bounding the regular expression (often <tt><font size=+1>/</font></tt>) and to <tt><font size=+1>\</font></tt> itself. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - To understand addressing in <i>ed</i> it is necessary to know that at - any time there is a <i>current line.</i> Generally, the current line - is the last line affected by a command; however, the exact effect - on the current line is discussed under the description of each - command. Addresses are constructed as follows. - 1. The character <tt><font size=+1>.</font></tt>, customarily called ‘dot’, addresses the current - line.<br> - 2. The character <tt><font size=+1>$</font></tt> addresses the last line of the buffer.<br> - 3. A decimal number <i>n</i> addresses the <i>n</i>-th line of the buffer.<br> - 4.<tt><font size=+1> 'x</font></tt> addresses the line marked with the name <i>x</i>, which must be - a lower-case letter. Lines are marked with the <tt><font size=+1>k</font></tt> command.<br> - 5. A regular expression enclosed in slashes ( <tt><font size=+1>/</font></tt>) addresses the - line found by searching forward from the current line and stopping - at the first line containing a string that matches the regular - expression. If necessary the search wraps around to the beginning - of the buffer.<br> - 6. A regular expression enclosed in queries <tt><font size=+1>?</font></tt> addresses the line - found by searching backward from the current line and stopping - at the first line containing a string that matches the regular - expression. If necessary the search wraps around to the end of - the buffer.<br> - 7. An address followed by a plus sign <tt><font size=+1>+</font></tt> or a minus sign <tt><font size=+1>−</font></tt> followed - by a decimal number specifies that address plus (resp. minus) - the indicated number of lines. The plus sign may be omitted.<br> - 8. An address followed by <tt><font size=+1>+</font></tt> (or <tt><font size=+1>−</font></tt>) followed by a regular expression - enclosed in slashes specifies the first matching line following - (or preceding) that address. The search wraps around if necessary. - The <tt><font size=+1>+</font></tt> may be omitted, so <tt><font size=+1>0/x/</font></tt> addresses the <i>first</i> line in the - buffer with an <tt><font size=+1>x</font></tt>.

If an address begins with <tt><font size=+1>+</font></tt> or <tt><font size=+1>−</font></tt> the addition or subtraction - is taken with respect to the current line; e.g. <tt><font size=+1>−5</font></tt> is understood - to mean <tt><font size=+1>.−5</font></tt>.<br> - 10. If an address ends with <tt><font size=+1>+</font></tt> or <tt><font size=+1>−</font></tt>, then 1 is added (resp. subtracted). - As a consequence of this rule and rule 9, the address <tt><font size=+1>−</font></tt> refers - to the line before the current line. Moreover, trailing <tt><font size=+1>+</font></tt> and - <tt><font size=+1>−</font></tt> characters have cumulative effect, so <tt><font size=+1>−−</font></tt> refers to the current - line less 2.<br> - 11.

size=+1><b>DESCRIPTION </b></font><br> - -<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> - - Plan 9 is a distributed computing environment built at Bell Labs - starting in the late 1980s. The system can be obtained from Bell - Labs at <tt><font size=+1>http://plan9.bell−labs.com/plan9</font></tt> and runs on PCs and a - variety of other platforms. Plan 9 became a convenient platform - for experimenting with new ideas, - applications, and services. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Plan 9 from User Space provides many of the ideas, applications, - and services from Plan 9 on Unix-like systems. It runs on FreeBSD - (x86), Linux (x86 and PowerPC), Mac OS X (PowerPC), OpenBSD (x86), - and SunOS (Sparc).<br> - <p><font size=+1><b>Commands </b></font><br> - Plan 9 from User Space expects its own directory tree, conventionally - <tt><font size=+1>/usr/local/plan9</font></tt>. When programs need to access files in the tree, - they expect the <tt><font size=+1>$PLAN9</font></tt> environment variable to contain the name - of the root of the tree. See <a href="../man1/install.html"><i>install</i>(1)</a> for details about installation. - - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Many of the familiar Unix commands, for example <a href="../man1/cat.html"><i>cat</i>(1)</a>, <a href="../man1/ls.html"><i>ls</i>(1)</a>, - and <a href="../man1/wc.html"><i>wc</i>(1)</a>, are present, but in their Plan 9 forms: <i>cat</i> takes no - arguments, <i>ls</i> does not columnate its output when printing to a - terminal, and <i>wc</i> counts UTF characters. In some cases, the differences - are quite noticeable: <a href="../man1/grep.html"><i>grep</i>(1)</a> and <a href="../man1/sed.html"><i>sed</i>(1)</a> expect Plan 9 - regular expressions (see <a href="../man7/regexp.html"><i>regexp</i>(7)</a>), which are closest to what - Unix calls extended regular expressions. Because of these differences, - it is not recommended to put <tt><font size=+1>$PLAN9/bin</font></tt> before the usual system - <tt><font size=+1>bin</font></tt> directories in your search path. Instead, put it at the end - of your path and use the <a href="../man1/9.html"><i>9</i>(1)</a> script when you want to - invoke the Plan 9 version of a traditional Unix command. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Occasionally the Plan 9 programs have been changed to adapt to - Unix. <a href="../man1/Mk.html"><i>Mk</i>(1)</a> now allows mkfiles to choose their own shell, and - <a href="../man1/rc.html"><i>rc</i>(1)</a> has a <i>ulimit</i> builtin and manages <tt><font size=+1>$PATH</font></tt>. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Many of the graphical programs from Plan 9 are present, including - <a href="../man1/sam.html"><i>sam</i>(1)</a> and <a href="../man1/acme.html"><i>acme</i>(1)</a>. An X11 window manager <a href="../man1/rio.html"><i>rio</i>(1)</a> mimics Plan 9’s - window system, with command windows implemented by the external - program <a href="../man1/9term.html"><i>9term</i>(1)</a>. Following the style of X Windows, these programs - run in new windows rather than the one in - which they are invoked. They all take a <tt><font size=+1>−W</font></tt> option to specify the - size and placement of the new window. The argument is one of <i>width</i><tt><font size=+1>x</font></tt><i>height</i>, - <i>width</i><tt><font size=+1>x</font></tt><i>height</i><tt><font size=+1>@</font></tt><i>xmin</i><tt><font size=+1>,</font></tt><i>xmax</i>, or <i>xmin</i><tt><font size=+1>,</font></tt><i>ymin</i><tt><font size=+1>,</font></tt><i>xmax</i><tt><font size=+1>,</font></tt><i>ymax</i>. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The <a href="../man4/plumber.html"><i>plumber</i>(4)</a> helps to connect the various Plan 9 programs together, - and fittings like <a href="../man1/web.html"><i>web</i>(1)</a> connect it to external programs such - as web browsers; one can click on a URL in <i>acme</i> and see the page - load in <i>Firefox</i>.<br> - <p><font size=+1><b>User-level file servers </b></font><br> - In Plan 9, user-level file servers present file trees via the - Plan 9 file protocol, 9P. Processes can mount arbitrary file servers - and customize their own name spaces. These facilities are used - to connect programs. Clients interact with file servers by reading - and writing files. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - This cannot be done directly on Unix. Instead the servers listen - for 9P connections on Unix domain sockets; clients connect to - these sockets and speak 9P directly using the <a href="../man3/9pclient.html"><i>9pclient</i>(3)</a> library. - <a href="../man4/Intro.html"><i>Intro</i>(4)</a> tells more of the story. The effect is not as clean as - on Plan 9, but it gets the job done and still provides a uniform - and - easy-to-understand mechanism. The <a href="../man1/9p.html"><i>9p</i>(1)</a> client can be used in - shell scripts or by hand to carry out simple interactions with - servers.<br> - <p><font size=+1><b>External databases </b></font><br> - Some programs rely on large databases that would be cumbersome - to include in every release. Scripts are provided that download - these databases separately. These databases can be downloaded - separately. See <tt><font size=+1>$PLAN9/dict/README</font></tt> and <tt><font size=+1>$PLAN9/sky/README</font></tt>.<br> - <p><font size=+1><b>Programming </b></font><br> - The shell scripts <i>9c</i> and <i>9l</i> (see <a href="../man1/9c.html"><i>9c</i>(1)</a>) provide a simple interface - to the underlying system compiler and linker, similar to the <i>2c</i> - and <i>2l</i> families on Plan 9. <i>9c</i> compiles source files, and <i>9l</i> links - object files into executables. When using Plan 9 libraries, <i>9l</i> - infers the correct set of libraries from the object files, so - that no <tt><font size=+1>−l - </font></tt>options are needed. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The only way to write multithreaded programs is to use the <a href="../man3/thread.html"><i>thread</i>(3)</a> - library. <a href="../man3/Rfork.html"><i>Rfork</i>(3)</a> exists but is not as capable as on Plan 9. There - are many unfortunate by necessary preprocessor diversions to make - Plan 9 and Unix libraries coexist. See <a href="../man3/intro.html"><i>intro</i>(3)</a> for details. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The debuggers <a href="../man1/acid.html"><i>acid</i>(1)</a> and <a href="../man1/db.html"><i>db</i>(1)</a> and the debugging library <a href="../man3/mach.html"><i>mach</i>(3)</a> - are works in progress. They are platform-independent, so that - x86 Linux core dumps can be inspected on PowerPC Mac OS X machines, - but they are also fairly incomplete.

Currently, - the only aggregates supported are <i>9ar</i> (see <a href="../man1/9c.html"><i>9c</i>(1)</a>) archives.<br> - <p><font size=+1><b>Attributes </b></font><br> - The colon separating the target from the prerequisites may be - immediately followed by <i>attributes</i> and another colon. The attributes - are:<br> - <tt><font size=+1>D</font></tt> If the recipe exits with a non-null status, the target is deleted.<br> - <tt><font size=+1>E</font></tt> Continue execution if the recipe draws errors.<br> - <tt><font size=+1>N</font></tt> If there is no recipe, the target has its time updated.<br> - <tt><font size=+1>n</font></tt> The rule is a meta-rule that cannot be a target of a virtual - rule. Only files match the pattern in the target.<br> - <tt><font size=+1>P</font></tt> The characters after the <tt><font size=+1>P</font></tt> until the terminating <tt><font size=+1>:</font></tt> are taken - as a program name. It will be invoked as <tt><font size=+1>sh −c prog 'arg1' 'arg2'</font></tt> - and should return a zero exit status if and only if arg1 is up - to date with respect to arg2. Date stamps are still propagated - in the normal way.<br> - <tt><font size=+1>Q</font></tt> The recipe is not printed prior to execution.<br> - <tt><font size=+1>R</font></tt> The rule is a meta-rule using regular expressions. In the rule, - <tt><font size=+1>%</font></tt> has no special meaning. The target is interpreted as a regular - expression as defined in <a href="../man7/regexp.html"><i>regexp</i>(7)</a>.

It modifies a local copy of an external - file. The copy is here called a <i>file</i>. The files are listed in - a menu available through mouse button 3 or the <tt><font size=+1>n</font></tt> command. Each - file has an associated name, usually the name of the external - file from which it was read, and a ‘modified’ bit that indicates - whether the editor’s file agrees with the external file. The external - file is not read into the editor’s file until it first becomes - the current file--that to which editing commands apply--whereupon - its menu entry is printed. The options are<br> - <tt><font size=+1>−d</font></tt> Do not ‘download’ the terminal part of <i>sam</i>.

Braces - may be nested arbitrarily. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - When a command makes a number of changes to a file, as in <tt><font size=+1>x/re/c/text/</font></tt>, - the addresses of all changes to the file are computed in the original - file. If the changes are in sequence, they are applied to the - file. Successive insertions at the same address are catenated - into a single insertion composed of the several - insertions in the order applied.<br> - <p><font size=+1><b>The terminal </b></font><br> - What follows refers to behavior of <i>sam</i> when downloaded, that is, - when operating as a display editor on a raster display. This is - the default behavior; invoking <i>sam</i> with the <tt><font size=+1>−d</font></tt> (no download) option - provides access to the command language only. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Each file may have zero or more windows open. Each window is equivalent - and is updated simultaneously with changes in other windows on - the same file. Each window has an independent value of dot, indicated - by a highlighted substring on the display. Dot may be in a region - not within the window. There is usually - a ‘current window’, marked with a dark border, to which typed - text and editing commands apply. Text may be typed and edited - as in <a href="../man1/rio.html"><i>rio</i>(1)</a>; also the escape key (ESC) selects (sets dot to) - text typed since the last mouse button hit. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The button 3 menu controls window operations. The top of the menu - provides the following operators, each of which uses one or more - <i>rio</i>-like cursors to prompt for selection of a window or sweeping - of a rectangle. ‘Sweeping’ a null rectangle gets a large window, - disjoint from the command window or the whole - screen, depending on where the null rectangle is.<br> - <tt><font size=+1>new</font></tt> Create a new, empty file.<br> - <tt><font size=+1>zerox</font></tt> Create a copy of an existing window.<br> - <tt><font size=+1>resize</font></tt> As in <i>rio</i>.<br> - <tt><font size=+1>close</font></tt> Delete the window. In the last window of a file, <tt><font size=+1>close</font></tt> is - equivalent to a <tt><font size=+1>D</font></tt> for the file.<br> - <tt><font size=+1>write</font></tt> Equivalent to a <tt><font size=+1>w</font></tt> for the file. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Below these operators is a list of available files, starting with - <tt><font size=+1>~~sam~~</font></tt>, the command window. Selecting a file from the list makes - the most recently used window on that file current, unless it - is already current, in which case selections cycle through the - open windows. If no windows are open on the file, the user is - prompted to open one. Files other than <tt><font size=+1>~~sam~~</font></tt> are marked with - one of the characters <tt><font size=+1>−+*</font></tt> according as zero, one, or more windows - are open on the file. A further mark <tt><font size=+1>.</font></tt> appears on the file in - the current window and a single quote, <tt><font size=+1>'</font></tt>, on a file modified since - last write. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The command window, created automatically when <tt><font size=+1>sam</font></tt> starts, is - an ordinary window except that text typed to it is interpreted - as commands for the editor rather than passive text, and text - printed by editor commands appears in it. The behavior is like - <i>rio</i>, with an ‘output point’ that separates commands being typed - from previous output. Commands typed in the command window apply - to the current open file--the file in the most recently current - window.<br> - <p><font size=+1><b>Manipulating text </b></font><br> - Button 1 changes selection, much like <i>rio</i>. Pointing to a non-current - window with button 1 makes it current; within the current window, - button 1 selects text, thus setting dot. Double-clicking selects - text to the boundaries of words, lines, quoted strings or bracketed - strings, depending on the text at the click. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Button 2 provides a menu of editing commands:<br> - <tt><font size=+1>cut</font></tt> Delete dot and save the deleted text in the snarf buffer.<br> - <tt><font size=+1>paste</font></tt> Replace the text in dot by the contents of the snarf buffer.<br> - <tt><font size=+1>snarf</font></tt> Save the text in dot in the snarf buffer.<br> - <tt><font size=+1>plumb</font></tt> Send the text in the selection as a plumb message.

- <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - A <tt><font size=+1>CFsys*</font></tt> represents a connection to a 9P server. A <tt><font size=+1>CFid*</font></tt> represents - an active fid on some connection; see <i>intro</i>(9p). - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - A new connection to a 9P server is typically established by <i>fsmount</i> - or <i>nsmount</i>. <i>Fsmount</i> initializes a new 9P conversation on the open - file descriptor <i>fd</i>; <i>nsmount</i> connects to a service named <i>name</i> in - the current name space directory (see <a href="../man4/intro.html"><i>intro</i>(4)</a>). Both attach to - the root of the file system using the attach name <i>aname</i>. - <i>Fsroot</i> returns the <tt><font size=+1>CFid*</font></tt> corresponding to this root. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Fsinit</i>, <i>fsversion</i>, <i>fsauth</i>, <i>fsattach</i>, and <i>fssetroot</i> provide more - detailed control over the file system connection than <i>fsmount</i> - and <i>nsmount</i>. <i>Fsinit</i> allocates a new <tt><font size=+1>CFsys*</font></tt> corresponding to a - 9P conversation on the file descriptor <i>fd</i>. <i>Fsversion</i> executes - a <i>version</i>(9p) transaction to establish maximum message size and - 9P - version. <i>Fsauth</i> executes an <i>auth</i>(9p) transaction, returning the - new auth fid. (<i>Fsread</i> and <i>fswrite</i> can then be used to run the - authentication protocol over the fid.) <i>Fsattach</i> executes an <i>attach</i>(9p) - transaction to connect to the root of a file tree served by the - server. It presents <i>afid</i> (which may be nil) to establish - identity. <i>Fssetroot</i> sets the root fid used by <i>fsopen</i>, <i>fsopenfd</i>, - <i>fsdirstat</i>, and <i>fsdirwstat</i>, which evaluate rooted path names. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - When a fid is no longer needed, it should be clunked by calling - <i>fsclose</i> and then considered freed. Similarly, when the connection - to the server is no longer needed, it should be closed by calling - <i>fsunmount</i>, which will take care of calling <i>fsclose</i> on the current - root fid. Once all fids have been clunked <i>and</i> the connection - has been closed (the order is not important), the allocated structures - will be freed and the file descriptor corresponding to the connection - will be closed (see <a href="../man2/close.html"><i>close</i>(2)</a>). Fids are not reference counted: - when <i>fsclose</i> is called, the clunk transaction and freeing of storage - happen immediately. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Fscreate</i> and <i>fsopen</i> establish new fids using the <i>walk</i>, <i>create</i> - and <i>open</i> transactions (see <i>walk</i>(9p) and <i>open</i>(9p)). The <i>path</i> argument - is evaluated relative to the <tt><font size=+1>CFsys</font></tt> root (see <i>fsroot</i> and <i>fssetroot</i> - above). The path is parsed as a slash-separated sequence of path - elements, as on Unix and Plan 9. Elements that are - empty or dot (<tt><font size=+1>.</font></tt>) are ignored. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Once opened, these fids can be read and written using <i>fspread</i> - and <i>fspwrite</i>, which execute <i>read</i> and <i>write</i> transactions (see <i>read</i>(9p)). - The library maintains an offset for each fid, analagous to the - offset maintained by the kernel for each open file descriptor. - <i>Fsread</i> and <i>fswrite</i> read and write from this offset, and - update it after successful calls. Calling <i>fspread</i> or <i>fspwrite</i> - with an <i>offset</i> of –1 is identical to calling <i>fsread</i> or <i>fswrite</i>. - <i>Fsreadn</i> calls <i>fsread</i> repeatedly to obtain exactly <i>n</i> bytes of data, - unless it encounters end-of-file or an error. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Reading an open a directory returns directory entries encoded - as described in <i>stat</i>(9p). <i>Fsdirread</i> calls <i>fsread</i> and then parses - the encoded entries into an array of <tt><font size=+1>Dir*</font></tt> data structures, storing - a pointer to the array in <tt><font size=+1>*d</font></tt> and returning the number of entries. - <i>Fsdirreadall</i> is similar but reads the entire directory. The - returned pointer should be freed with <i>free</i> (see <a href="../man3/malloc.html"><i>malloc</i>(3)</a>) when - no longer needed. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Fsdirfstat</i> and <i>fsdirfwstat</i> execute <i>stat</i> and <i>wstat</i> (see <i>stat</i>(9p)) - transactions.

A proxy - process on the other end is ferrying data between the pipe and - the 9P fid. Because of the implementation as a pipe, the only - signal of a - read or write error is the closing of the pipe.

- <i>Deflate</i> compresses input data retrieved by calls to <i>r</i> with arguments - <i>rr</i>, an input buffer, and a count of bytes to read. <i>R</i> should return - the number of bytes read; end of input is signaled by returning - zero, an input error by returning a negative number. The compressed - output is written to <i>w</i> with arguments <i>wr</i>, the - output data, and the number of bytes to write. <i>W</i> should return - the number of bytes written; writing fewer than the requested - number of bytes is an error. <i>Level</i> indicates the amount of computation - deflate should do while compressing the data. Higher <i>levels</i> usually - take more time and produce smaller outputs. Valid - values are 1 to 9, inclusive; 6 is a good compromise. If <i>debug</i> - is non-zero, cryptic debugging information is produced on standard - error. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Inflate</i> reverses the process, converting compressed data into - uncompressed output.

In essence, they provide access - to the workings of the formatted print code. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The <a href="../man3/print.html"><i>print</i>(3)</a> suite maintains its state with a data structure called - <tt><font size=+1>Fmt</font></tt>. A typical call to <a href="../man3/print.html"><i>print</i>(3)</a> or its relatives initializes a - <tt><font size=+1>Fmt</font></tt> structure, passes it to subsidiary routines to process the - output, and finishes by emitting any saved state recorded in the - <tt><font size=+1>Fmt</font></tt>. The details of the <tt><font size=+1>Fmt</font></tt> are unimportant to outside users, - except - insofar as the general design influences the interface. The <tt><font size=+1>Fmt</font></tt> - records whether the output is in runes or bytes, the verb being - processed, its precision and width, and buffering parameters. - Most important, it also records a <i>flush</i> routine that the library - will call if a buffer overflows. When printing to a file descriptor, - the - flush routine will emit saved characters and reset the buffer; - when printing to an allocated string, it will resize the string - to receive more output. The flush routine is nil when printing - to fixed-size buffers. User code need never provide a flush routine; - this is done internally by the library.<br> - <p><font size=+1><b>Custom output routines </b></font><br> - To write a custom output routine, such as an error handler that - formats and prints custom error messages, the output sequence - can be run from outside the library using the routines described - here. There are two main cases: output to an open file descriptor - and output to a string. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - To write to a file descriptor, call <i>fmtfdinit</i> to initialize the - local <tt><font size=+1>Fmt</font></tt> structure <i>f</i>, giving the file descriptor <i>fd</i>, the buffer - <i>buf</i>, and its size <i>nbuf</i>. Then call <i>fmtprint</i> or <i>fmtvprint</i> to generate - the output.

The arguments to <i>initdraw</i> include a <i>label</i>, - which is written to <tt><font size=+1>/dev/label</font></tt> if non-nil so that it can be used - to identify the window when hidden (see <a href="../man1/rio.html"><i>rio</i>(1)</a>). The font is created - by reading the named <i>font</i> file. If <tt><font size=+1>font</font></tt> is null, <i>initdraw</i> reads - the file named in the environment variable <tt><font size=+1>$font</font></tt>; if - <tt><font size=+1>$font</font></tt> is not set, it imports the default (usually minimal) font - from the operating system. The global <i>font</i> will be set to point - to the resulting <tt><font size=+1>Font</font></tt> structure. The <i>errfun</i> argument is a <i>graphics - error function</i> to call in the event of a fatal error in the library; - it must never return. Its arguments are the display pointer - and an error string. If <i>errfun</i> is nil, the library provides a - default, called <i>drawerror</i>. Another effect of <i>initdraw</i> is that - it installs <a href="../man3/print.html"><i>print</i>(3)</a> formats <i>Pfmt</i> and <i>Rfmt</i> as <tt><font size=+1>%P</font></tt> and <tt><font size=+1>%R</font></tt> for printing - <tt><font size=+1>Points</font></tt> and <tt><font size=+1>Rectangles</font></tt>. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The <i>geninitdraw</i> function provides a less automated way to establish - a connection, for programs that wish to connect to multiple displays. - <i>Devdir</i> is the name of the directory containing the device files - for the display (if nil, default <tt><font size=+1>/dev</font></tt>); <i>errfun</i>, <i>font</i>, and <i>label</i> - are as in <i>initdraw</i>; <i>mousedir</i> and <i>windir</i> are the directories - holding the <tt><font size=+1>mouse</font></tt> and <tt><font size=+1>winname</font></tt> files; and <i>ref</i> specifies the refresh - function to be used to create the window, if running under <a href="../man1/rio.html"><i>rio</i>(1)</a> - (see <a href="../man3/window.html"><i>window</i>(3)</a>). - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Initdisplay</i> is part of <i>geninitdraw</i>; it sets up the display structures - but does not allocate any fonts or call <i>getwindow</i>. The arguments - are similar to those of <i>initdraw</i>; <i>win</i> names the directory, default - <tt><font size=+1>/dev</font></tt>, in which the files associated with the window reside. <i>Closedisplay</i> - disconnects the display and frees the associated - data structures. <i>Getdefont</i> builds a <tt><font size=+1>Font</font></tt> structure from in-core - data describing a default font. None of these routines is needed - by most programs, since <i>initdraw</i> calls them as needed. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The data structures associated with the display must be protected - in a multi-process program, because they assume only one process - will be using them at a time. Multi-process programs should set - <tt><font size=+1>display−>locking</font></tt> to <tt><font size=+1>1</font></tt>, to notify the library to use a locking protocol - for its own accesses, and call <i>lockdisplay</i> and - <i>unlockdisplay</i> around any calls to the graphics library that will - cause messages to be sent to the display device. <i>Initdraw</i> and - <i>geninitdraw</i> initialize the display to the locked state. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Getwindow</i> returns a pointer to the window associated with the - application; it is called automatically by <i>initdraw</i> to establish - the <tt><font size=+1>screen</font></tt> pointer but must be called after each resizing of the - window to restore the library’s connection to the window. If <tt><font size=+1>rio</font></tt> - is not running, it returns <tt><font size=+1>display−>image</font></tt>; otherwise it - negotiates with <tt><font size=+1>rio</font></tt> by looking in <tt><font size=+1>/dev/winname</font></tt> to find the name - of the window and opening it using <tt><font size=+1>namedimage</font></tt> (see <a href="../man3/allocimage.html"><i>allocimage</i>(3)</a>). - The resulting window will be created using the refresh method - <i>ref</i> (see <a href="../man3/window.html"><i>window</i>(3)</a>); this should almost always be <tt><font size=+1>Refnone</font></tt> because - <tt><font size=+1>rio</font></tt> provides backing store for the window. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Getwindow</i> overwrites the global variables <tt><font size=+1>screen</font></tt>, a pointer to - the <tt><font size=+1>Image</font></tt> defining the window (or the overall display, if no window - system is running); and <tt><font size=+1>_screen</font></tt>, a pointer to the <tt><font size=+1>Screen</font></tt> representing - the root of the window’s hierarchy. (See <a href="../man3/window.html"><i>window</i>(3)</a>. The overloading - of the <tt><font size=+1>screen</font></tt> word is an unfortunate - historical accident.) <i>Getwindow</i> arranges that <tt><font size=+1>screen</font></tt> point to - the portion of the window inside the border; sophisticated clients - may use <tt><font size=+1>_screen</font></tt> to make further subwindows. <i>Gengetwindow</i>’s extra - arguments are the full path of the window’s <tt><font size=+1>winname</font></tt> file and pointers - to be overwritten with the values of the - ‘global’ <tt><font size=+1>Image</font></tt> and <tt><font size=+1>Screen</font></tt> variables for the new window. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The mouse cursor is always displayed.

The character set - of the document is described in <i>chset</i>, which can be - one of <tt><font size=+1>US_Ascii</font></tt>, <tt><font size=+1>ISO_8859_1</font></tt>, <tt><font size=+1>UTF_8</font></tt> or <tt><font size=+1>Unicode</font></tt>.

These routines are analogous - to the standard malloc and realloc routines, except that they - should not return if the memory allocation fails. In addition, - <tt><font size=+1>emalloc</font></tt> is required to zero the memory. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - For debugging purposes, <i>printitems</i> may be called to display the - contents of an item list; individual items may be printed using - the <tt><font size=+1>%I</font></tt> print verb, installed on the first call to <i>parsehtml</i>. <i>validitems</i> - traverses the item list, checking that all of the pointers are - valid. It returns <tt><font size=+1>1</font></tt> is everything is ok, and <tt><font size=+1>0</font></tt> if an error was - found. Normally, one would not call these routines directly. Instead, - one sets the global variable <i>dbgbuild</i> and the library calls them - automatically.

-<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> - - This section describes functions in various libraries. For the - most part, each library is defined by a single C include file, - such as those listed above, and a single archive file containing - the library proper. The name of the archive is <tt><font size=+1>/usr/local/plan9/lib/lib</font></tt><i>x</i><tt><font size=+1>.a</font></tt>, - where <i>x</i> is the base of the include file name, - stripped of a leading <tt><font size=+1>lib</font></tt> if present. For example, <tt><font size=+1><draw.h></font></tt> defines - the contents of library <tt><font size=+1>/usr/local/plan9/lib/libdraw.a</font></tt>, which - may be abbreviated when named to the loader as <tt><font size=+1>−ldraw</font></tt>. In practice, - each include file contains a magic pragma that directs the loader - to pick up the associated archive - automatically, so it is rarely necessary to tell the loader which - libraries a program needs; see <a href="../man1/9c.html"><i>9c</i>(1)</a>. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The library to which a function belongs is defined by the header - file that defines its interface. The ‘C library’, <i>libc</i>, contains - most of the basic subroutines such as <i>strlen</i>. Declarations for - all of these functions are in <tt><font size=+1><libc.h></font></tt>, which must be preceded by - (<i>needs</i>) an include of <tt><font size=+1><u.h></font></tt>. The graphics library, <i>draw</i>, is - defined by <tt><font size=+1><draw.h></font></tt>, which needs <tt><font size=+1><libc.h></font></tt> and <tt><font size=+1><u.h></font></tt>. The Buffered I/O - library, <i>libbio</i>, is defined by <tt><font size=+1><bio.h></font></tt>, which needs <tt><font size=+1><libc.h></font></tt> and <tt><font size=+1><u.h></font></tt>. - The ANSI C Standard I/O library, <i>libstdio</i>, is defined by <tt><font size=+1><stdio.h></font></tt>, - which needs <tt><font size=+1><u.h></font></tt>. There are a few other, less commonly used libraries - defined on - individual pages of this section. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The include file <tt><font size=+1><u.h></font></tt>, a prerequisite of several other include - files, declares the architecture-dependent and -independent types, - including: <i>uchar</i>, <i>ushort</i>, and <i>ulong</i>, the unsigned integer types; - <i>schar</i>, the signed char type; <i>vlong</i> and <i>uvlong</i>, the signed and - unsigned very long integral types; <i>Rune</i>, the Unicode - character type; <i>u8int</i>, <i>u16int</i>, <i>u32int</i>, and <i>u64int</i>, the unsigned - integral types with specific widths; <i>jmp_buf</i>, the type of the - argument to <i>setjmp</i> and <i>longjmp</i>, plus macros that define the layout - of <i>jmp_buf</i> (see <a href="../man3/setjmp.html"><i>setjmp</i>(3)</a>); and the macros <tt><font size=+1>va_arg</font></tt> and friends - for accessing arguments of variadic functions (identical to the - macros defined in <tt><font size=+1><stdarg.h></font></tt> in ANSI C). - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Plan 9 and Unix use many similarly-named functions for different - purposes: for example, Plan 9’s <i>dup</i> is closer to (but not exactly) - Unix’s <i>dup2</i>. To avoid name conflicts, <tt><font size=+1><libc.h></font></tt> defines many of these - names as preprocessor macros to add a <i>p9</i> prefix, so that <i>dup</i> becomes - <i>p9dup</i>. To disable this renaming, - <tt><font size=+1>#define NOPLAN9DEFINES</font></tt> before including <tt><font size=+1><libc.h></font></tt>. If Unix headers - must be included in a program, they should be included after <tt><font size=+1><u.h></font></tt>, - which sets important preprocessor directives (for example, to - enable 64-bit file offsets), but before <tt><font size=+1><libc.h></font></tt>, to avoid renaming - problems. - <p><font size=+1><b>Name space </b></font><br> - Files are collected into a hierarchical organization called a - <i>file tree</i> starting in a <i>directory</i> called the <i>root</i>. File names, - also called <i>paths</i>, consist of a number of <tt><font size=+1>/</font></tt>-separated <i>path elements</i> - with the slashes corresponding to directories. A path element - must contain only printable characters (those outside the control - spaces of ASCII and Latin-1). A path element cannot contain a - slash. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - When a process presents a file name to Plan 9, it is <i>evaluated</i> - by the following algorithm. Start with a directory that depends - on the first character of the path: <tt><font size=+1>/</font></tt> means the root of the main - hierarchy, and anything else means the process’s current working - directory. Then for each path element, look up the element in - the directory, advance to that directory, do a possible translation - (see below), and repeat. The last step may yield a directory or - regular file.<br> - <p><font size=+1><b>File I/O </b></font><br> - Files are opened for input or output by <i>open</i> or <i>create</i> (see <a href="../man3/open.html"><i>open</i>(3)</a>). - These calls return an integer called a <i>file descriptor</i> which identifies - the file to subsequent I/O calls, notably <a href="../man3/read.html"><i>read</i>(3)</a> and <i>write</i>. The - system allocates the numbers by selecting the lowest unused descriptor. - They are allocated dynamically; there is no - visible limit to the number of file descriptors a process may - have open. They may be reassigned using <a href="../man3/dup.html"><i>dup</i>(3)</a>. File descriptors - are indices into a kernel resident <i>file descriptor table</i>. Each - process has an associated file descriptor table. In threaded programs - (see <a href="../man3/thread.html"><i>thread</i>(3)</a>), the file descriptor table is shared by all the - procs. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - By convention, file descriptor 0 is the standard input, 1 is the - standard output, and 2 is the standard error output. With one - exception, the operating system is unaware of these conventions; - it is permissible to close file 0, or even to replace it by a - file open only for writing, but many programs will be confused - by such - chicanery. The exception is that the system prints messages about - broken processes to file descriptor 2. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Files are normally read or written in sequential order. The I/O - position in the file is called the <i>file offset</i> and may be set - arbitrarily using the <a href="../man3/seek.html"><i>seek</i>(3)</a> system call. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Directories may be opened like regular files. Instead of reading - them with <a href="../man3/read.html"><i>read</i>(3)</a>, use the <tt><font size=+1>Dir</font></tt> structure-based routines described - in <a href="../man3/dirread.html"><i>dirread</i>(3)</a>. The entry corresponding to an arbitrary file can - be retrieved by <i>dirstat</i> (see <a href="../man3/stat.html"><i>stat</i>(3)</a>) or <i>dirfstat</i>; <i>dirwstat</i> and - <i>dirfwstat</i> write back entries, thus changing the properties of - a - file. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - New files are made with <i>create</i> (see <a href="../man3/open.html"><i>open</i>(3)</a>) and deleted with - <a href="../man3/remove.html"><i>remove</i>(3)</a>. Directories may not directly be written; <i>create</i>, <i>remove</i>, - <i>wstat</i>, and <i>fwstat</i> alter them. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <a href="../man3/Pipe.html"><i>Pipe</i>(3)</a> creates a connected pair of file descriptors, useful for - bidirectional local communication.<br> - <p><font size=+1><b>Process execution and control </b></font><br> - A new process is created when an existing one calls <a href="../man2/fork.html"><i>fork</i>(2)</a>. The - new (child) process starts out with copies of the address space - and most other attributes of the old (parent) process. In particular, - the child starts out running the same program as the parent; <a href="../man3/exec.html"><i>exec</i>(3)</a> - will bring in a different one. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Each process has a unique integer process id; a set of open files, - indexed by file descriptor; and a current working directory (changed - by <a href="../man2/chdir.html"><i>chdir</i>(2)</a>). - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Each process has a set of attributes -- memory, open files, name - space, etc. -- that may be shared or unique. Flags to <i>rfork</i> control - the sharing of these attributes. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - A process terminates by calling <a href="../man3/exits.html"><i>exits</i>(3)</a>. A parent process may - call <a href="../man3/wait.html"><i>wait</i>(3)</a> to wait for some child to terminate. A bit of status - information may be passed from <i>exits</i> to <i>wait</i>. On Plan 9, the status - information is an arbitrary text string, but on Unix it is a single - integer. The Plan 9 interface persists here, although the - functionality does not. Instead, empty strings are converted to - exit status 0 and non-empty strings to 1. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - A process can go to sleep for a specified time by calling <a href="../man3/sleep.html"><i>sleep</i>(3)</a>. - - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - There is a <i>notification</i> mechanism for telling a process about - events such as address faults, floating point faults, and messages - from other processes. A process uses <a href="../man3/notify.html"><i>notify</i>(3)</a> to register the - function to be called (the <i>notification handler</i>) when such events - occur.<br> - <p><font size=+1><b>Multithreading </b></font><br> - Where possible according to the ANSI C standard, the main C library - works properly in multiprocess programs; <i>malloc</i>, <i>print</i>, and the - other routines use locks (see <a href="../man3/lock.html"><i>lock</i>(3)</a>) to synchronize access to - their data structures. The graphics library defined in <tt><font size=+1><draw.h></font></tt> - is also multi-process capable; details are in <a href="../man3/graphics.html"><i>graphics</i>(3)</a>. - In general, though, multiprocess programs should use some form - of synchronization to protect shared data. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The thread library, defined in <tt><font size=+1><thread.h></font></tt>, provides support for - multiprocess programs. It includes a data structure called a <tt><font size=+1>Channel</font></tt> - that can be used to send messages between processes, and coroutine-like - <i>threads</i>, which enable multiple threads of control within a single - process. The threads within a process - are scheduled by the library, but there is no pre-emptive scheduling - within a process; thread switching occurs only at communication - or synchronization points. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Most programs using the thread library comprise multiple processes - communicating over channels, and within some processes, multiple - threads. Since I/O calls may block, a system call may block all - the threads in a process. Therefore, a program that shouldn’t - block unexpectedly will use a process to serve the I/O - request, passing the result to the main processes over a channel - when the request completes. For examples of this design, see <a href="../man3/ioproc.html"><i>ioproc</i>(3)</a> - or <a href="../man3/mouse.html"><i>mouse</i>(3)</a>.<br> - -</table> -<p><font size=+1><b>SEE ALSO </b></font><br> - -<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> - - <a href="../man1/nm.html"><i>nm</i>(1)</a>, <a href="../man1/9c.html"><i>9c</i>(1)</a><br> - -</table> -<p><font size=+1><b>DIAGNOSTICS </b></font><br> - -<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> - - Math functions in <i>libc</i> return special values when the function - is undefined for the given arguments or when the value is not - representable (see <a href="../man3/nan.html"><i>nan</i>(3)</a>). - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Some of the functions in <i>libc</i> are system calls and many others - employ system calls in their implementation.

The caller may specify an initial - register set in the form of an <i>Rgetter</i> function, of the form - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - - <table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> - - <tt><font size=+1>ulong rget(Map *map, char *name)<br> - - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - </font></tt> - - </table> - It returns the contents of a register when given a map and a register - name.

- The <tt><font size=+1>Memimage</font></tt> type defines memory-resident rectangular pictures - and the methods to draw upon them; <tt><font size=+1>Memimage</font></tt>s differ from <tt><font size=+1>Image</font></tt>s - (see <a href="../man3/draw.html"><i>draw</i>(3)</a>) in that they are manipulated directly in user memory - rather than by RPCs to the <tt><font size=+1>/dev/draw</font></tt> hierarchy. The library is - the basis for the kernel <a href="../man3/draw.html"><i>draw</i>(3)</a> driver and also - used by a number of programs that must manipulate images without - a display. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The <tt><font size=+1>r, clipr</font></tt>, <tt><font size=+1>depth</font></tt>, <tt><font size=+1>nchan</font></tt>, and <tt><font size=+1>chan</font></tt> structure elements are identical - to the ones of the same name in the <tt><font size=+1>Image</font></tt> structure. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The <tt><font size=+1>flags</font></tt> element of the <tt><font size=+1>Memimage</font></tt> structure holds a number of - bits of information about the image. In particular, it subsumes - the purpose of the <tt><font size=+1>repl</font></tt> element of <tt><font size=+1>Image</font></tt> structures. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Memimageinit</i> initializes various static data that the library - depends on, as well as the replicated solid color images <tt><font size=+1>memopaque</font></tt>, - <tt><font size=+1>memtransparent</font></tt>, <tt><font size=+1>memblack</font></tt>, and <tt><font size=+1>memwhite</font></tt>. It should be called before - referring to any of these images and before calling any of the - other library functions. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Each <tt><font size=+1>Memimage</font></tt> points at a <tt><font size=+1>Memdata</font></tt> structure that in turn points - at the actual pixel data for the image. This allows multiple images - to be associated with the same <tt><font size=+1>Memdata</font></tt>. The first word of the - data pointed at by the <tt><font size=+1>base</font></tt> element of <tt><font size=+1>Memdata</font></tt> points back at - the <tt><font size=+1>Memdata</font></tt> structure, so that in the Plan 9 kernel, - the memory allocator (see Plan 9’s <i>pool</i>(3)) can compact image - memory using <i>memimagemove</i>. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Because images can have different coordinate systems, the <tt><font size=+1>zero</font></tt> - element of the <tt><font size=+1>Memimage</font></tt> structure contains the offset that must - be added to the <tt><font size=+1>bdata</font></tt> element of the corresponding <tt><font size=+1>Memdata</font></tt> structure - in order to yield a pointer to the data for the pixel (0,0). Adding - <tt><font size=+1>width</font></tt> machine words to this pointer moves it - down one scan line. The <tt><font size=+1>depth</font></tt> element can be used to determine - how to move the pointer horizontally. Note that this method works - even for images whose rectangles do not include the origin, although - one should only dereference pointers corresponding to pixels within - the image rectangle. <i>Wordaddr</i> and - <i>byteaddr</i> perform these calculations, returning pointers to the - word and byte, respectively, that contain the beginning of the - data for a given pixel. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Allocmemimage</i> allocages images with a given rectangle and channel - descriptor (see <tt><font size=+1>strtochan</font></tt> in <a href="../man3/graphics.html"><i>graphics</i>(3)</a>), creating a fresh <tt><font size=+1>Memdata</font></tt> - structure and associated storage. <i>Allocmemimaged</i> is similar but - uses the supplied <i>Memdata</i> structure rather than a new one. The - <i>readmemimage</i> function reads an - uncompressed bitmap from the given file descriptor, while <i>creadmemimage</i> - reads a compressed bitmap. <i>Writememimage</i> writes a compressed representation - of <i>i</i> to file descriptor <i>fd</i>. For more on bitmap formats, see <a href="../man7/image.html"><i>image</i>(7)</a>. - <i>Freememimage</i> frees images returned by any of these routines. The - <tt><font size=+1>Memimage</font></tt> structure - contains some tables that are used to store precomputed values - depending on the channel descriptor. <i>Memsetchan</i> updates the <tt><font size=+1>chan</font></tt> - element of the structure as well as these tables, returning –1 - if passed a bad channel descriptor. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Loadmemimage</i> and <i>cloadmemimage</i> replace the pixel data for a given - rectangle of an image with the given buffer of uncompressed or - compressed data, respectively.

Threads and procs - occupy a shared address space, communicating and synchronizing - through <i>channels</i> and shared variables. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - A <i>proc</i> is a Plan 9 process that contains one or more cooperatively - scheduled <i>threads</i>. Programs using threads must replace <i>main</i> by - <i>threadmain</i>. The thread library provides a <i>main</i> function that sets - up a proc with a single thread executing <i>threadmain</i> on a stack - of size <i>mainstacksize</i> (default eight kilobytes). To set - <i>mainstacksize</i>, declare a global variable initialized to the desired - value (<i>e.g.</i>, <tt><font size=+1>int mainstacksize = 1024</font></tt>). - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Threadcreate</i> creates a new thread in the calling proc, returning - a unique integer identifying the thread; the thread executes <i>fn(arg)</i> - on a stack of size <i>stacksize</i>. Thread stacks are allocated in shared - memory, making it valid to pass pointers to stack variables between - threads and procs. <i>Proccreate</i> creates a new proc, - and inside that proc creates a single thread as <i>threadcreate</i> would, - returning the id of the created thread. Be aware that the calling - thread may continue execution before the newly created proc and - thread are scheduled. Because of this, <i>arg</i> should not point to - data on the stack of a function that could return before the - new process is scheduled. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Threadexits</i> terminates the calling thread. If the thread is the - last in its proc, <i>threadexits</i> also terminates the proc, using - <i>status</i> as the exit status. <i>Threadexitsall</i> terminates all procs - in the program, using <i>status</i> as the exit status. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - When the last thread in <i>threadmain</i>’s proc exits, the program will - appear to its parent to have exited. The remaining procs will - still run together, but as a background program. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The threads in a proc are coroutines, scheduled nonpreemptively - in a round-robin fashion. A thread must explicitly relinquish - control of the processor before another thread in the same proc - is run. Calls that do this are <i>yield</i>, <i>proccreate</i>, <i>threadexec</i>, - <i>threadexecl</i>, <i>threadexits</i>, <i>threadspawn</i>, <i>alt</i>, <i>send</i>, and <i>recv</i> (and - the - calls related to <i>send</i> and <i>recv</i>--see their descriptions further on). - Procs are scheduled by the operating system. Therefore, threads - in different procs can preempt one another in arbitrary ways and - should synchronize their actions using <tt><font size=+1>qlocks</font></tt> (see <a href="../man3/lock.html"><i>lock</i>(3)</a>) or - channel communication. System calls such as <a href="../man3/read.html"><i>read</i>(3)</a> - block the entire proc; all threads in a proc block until the system - call finishes. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - As mentioned above, each thread has a unique integer thread id. - Thread ids are not reused; they are unique across the life of - the program. <i>Threadid</i> returns the id for the current thread. Each - thread also has a thread group id. The initial thread has a group - id of zero. Each new thread inherits the group id of the - thread that created it. <i>Threadgrp</i> returns the group id for the - current thread; <i>threadsetgrp</i> sets it. <i>Threadpid</i> returns the pid - of the Plan 9 process containing the thread identified by <i>id</i>, - or –1 if no such thread is found. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Threadint</i> interrupts a thread that is blocked in a channel operation - or system call. <i>Threadintgrp</i> interrupts all threads with the given - group id. <i>Threadkill</i> marks a thread to die when it next relinquishes - the processor (via one of the calls listed above). If the thread - is blocked in a channel operation or system call, it is - also interrupted. <i>Threadkillgrp</i> kills all threads with the given - group id. Note that <i>threadkill</i> and <i>threadkillgrp</i> will not terminate - a thread that never relinquishes the processor. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Primarily for debugging, threads can have string names associated - with them. <i>Threadgetname</i> returns the current thread’s name; <i>threadsetname</i> - sets it. The pointer returned by <i>threadgetname</i> is only valid until - the next call to <i>threadsetname</i>. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Also for debugging, threads have a string state associated with - them. <i>Threadsetstate</i> sets the state string. There is no <i>threadgetstate</i>; - since the thread scheduler resets the state to <tt><font size=+1>Running</font></tt> every time - it runs the thread, it is only useful for debuggers to inspect - the state. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Threaddata</i> returns a pointer to a per-thread pointer that may - be modified by threaded programs for per-thread storage. Similarly, - <i>procdata</i> returns a pointer to a per-proc pointer. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Threadexecl</i> and <i>threadexec</i> are threaded analogues of <i>exec</i> and - <i>execl</i> (see <a href="../man3/exec.html"><i>exec</i>(3)</a>); on success, they replace the calling thread - and invoke the external program, never returning. (Unlike on Plan - 9, the calling thread need not be the only thread in its proc--the - other threads will continue executing.) On error, they return - –1. If <i>cpid</i> is not null, the pid of the invoked program will be - sent along <i>cpid</i> (using <i>sendul</i>) once the program has been started, - or –1 will be sent if an error occurs. <i>Threadexec</i> and <i>threadexecl</i> - will not access their arguments after sending a result along <i>cpid</i>. - Thus, programs that malloc the <i>argv</i> passed to <i>threadexec - </i>can safely free it once they have received the <i>cpid</i> response. - - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Threadexecl</i> and <i>threadexec</i> will duplicate (see <a href="../man3/dup.html"><i>dup</i>(3)</a>) the three - file descriptors in <i>fd</i> onto standard input, output, and error - for the external program and then close them in the calling thread. - Beware of code that sets<br> - - <table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> - - <tt><font size=+1>fd[0] = 0;<br> - fd[1] = 1;<br> - fd[2] = 2;<br> - - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - </font></tt> - - </table> - to use the current standard files.

When an exec’ed process exits, a pointer to a <tt><font size=+1>Waitmsg</font></tt> - is sent to this channel. These <tt><font size=+1>Waitmsg</font></tt> structures have been allocated - with <a href="../man3/malloc.html"><i>malloc</i>(3)</a> and should be freed after use. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - A <tt><font size=+1>Channel</font></tt> is a buffered or unbuffered queue for fixed-size messages. - Procs and threads <i>send</i> messages into the channel and <i>recv</i> messages - from the channel. If the channel is unbuffered, a <i>send</i> operation - blocks until the corresponding <i>recv</i> operation occurs and <i>vice - versa</i>. <i>Chaninit</i> initializes a <tt><font size=+1>Channel</font></tt> for - messages of size <i>elsize</i> and with a buffer holding <i>nel</i> messages. - If <i>nel</i> is zero, the channel is unbuffered. <i>Chancreate</i> allocates - a new channel and initializes it. <i>Chanfree</i> frees a channel that - is no longer used. <i>Chanfree</i> can be called by either sender or - receiver after the last item has been sent or received.

If <i>v</i> - is null, zeros are sent. <i>Recv</i> receives an element from <i>c</i> and stores - it in <i>v</i>. If <i>v</i> is null, the received value is discarded. <i>Send</i> and - <i>recv</i> return 1 on success, –1 if interrupted. <i>Nbsend</i> and <i>nbrecv</i> - behave similarly, but return 0 rather than blocking. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Sendp</i>, <i>nbsendp</i>, <i>sendul</i>, and <i>nbsendul</i> send a pointer or an unsigned - long; the channel must have been initialized with the appropriate - <i>elsize</i>. <i>Recvp</i>, <i>nbrecvp</i>, <i>recvul</i>, and <i>nbrecvul</i> receive a pointer - or an unsigned long; they return zero when a zero is received, - when interrupted, or (for <i>nbrecvp</i> and <i>nbrecvul</i>) when the - operation would have blocked. To distinguish between these three - cases, use <i>recv</i> or <i>nbrecv</i>. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Alt</i> can be used to recv from or send to one of a number of channels, - as directed by an array of <tt><font size=+1>Alt</font></tt> structures, each of which describes - a potential send or receive operation. In an <tt><font size=+1>Alt</font></tt> structure, <tt><font size=+1>c</font></tt> - is the channel; <tt><font size=+1>v</font></tt> the value pointer (which may be null); and <tt><font size=+1>op</font></tt> - the operation: <tt><font size=+1>CHANSND</font></tt> for a send operation, - <tt><font size=+1>CHANRECV</font></tt> for a recv operation; <tt><font size=+1>CHANNOP</font></tt> for no operation (useful - when <i>alt</i> is called with a varying set of operations). The array - of <tt><font size=+1>Alt</font></tt> structures is terminated by an entry with <i>op</i> <tt><font size=+1>CHANEND</font></tt> or - <tt><font size=+1>CHANNOBLK</font></tt>.

This section - of the manual describes servers that can be mounted in a name - space to give a file-like interface to interesting services. A - file server may be a provider of a conventional file system, with - files maintained on permanent storage, or it may also be a process - that synthesizes files in some manner. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - In Plan 9, the kernel mount device <i>mnt</i>(3) acts as a client to - the 9P servers mounted in the current name space, translating - system calls such as <a href="../man2/open.html"><i>open</i>(2)</a> into 9P transactions such as <i>open</i>(9p). - The kernel also multiplexes the potentially many processes onto - a single 9P conversation with each server. Finally, the kernel - provides each process with its own private <i>name space</i> which it - can customize at will. Modern Unix systems do not provide these - niceties, so the Unix port of these Plan 9 file servers provides - them via other means. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - On Unix, 9P clients do not access servers via the traditional - file system call interface. Only the Unix name space can be accessed - that way. Instead, 9P clients use the <a href="../man3/9pclient.html"><i>9pclient</i>(3)</a> library to connect - and interact directly with particular 9P servers. The <a href="../man1/9p.html"><i>9p</i>(1)</a> command-line - client is useful for interactive use and in shell - scripts. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - To preserve the façade of a single 9P conversation with each server, - 9P servers invoke <a href="../man4/9pserve.html"><i>9pserve</i>(4)</a>, typically via <a href="../man3/post9pservice.html"><i>post9pservice</i>(3)</a>. - <i>9pserve</i> announces a 9P service at a particular network address - and multiplexes the clients that connect to that address onto - a single 9P conversation with the server. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Each ported program operates in a pseudo-name space that determines - which 9P servers it is using. The name space of a ported program - is represented by a directory containing Unix domain sockets, - one for each 9P server. The directory defaults to <tt><font size=+1>/tmp/ns.$USER.$DISPLAY</font></tt>, - meaning that all programs in an X - Windows login session share a single name space. Setting the <tt><font size=+1>$NAMESPACE</font></tt> - environment variable overrides this default. The <a href="../man1/namespace.html"><i>namespace</i>(1)</a> - command prints the current name space directory. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Occasionally it is useful to be able to connect the input or output - of a standard Unix program to a file served by a 9P server. The - new <i>openfd</i>(9p) 9P transaction, which depends on file descriptor - passing, provides a sufficient workaround in many cases. <i>9pserve</i>’s - implementation of <i>openfd</i> (see also <i>fsopenfd</i> in - <a href="../man3/9pclient.html"><i>9pclient</i>(3)</a>) returns the read or write end of a pipe; a helper - process transfers data between the other end of the pipe and the - 9P server. Note that since the data is being transferred via a - pipe, 9P read and write errors cannot be passed on to the Unix - program. The Unix program sees only end-of-file or a closed pipe. - -</table> - -<td width=20> -<tr height=20><td> -</table> -<!-- TRAILER --> -<table border=0 cellpadding=0 cellspacing=0 width=100%> -<tr height=15><td width=10><td><td width=10> -<tr><td><td> -<center> -<a href="../../"><img src="../../dist/spaceglenda100.png" alt="Space Glenda" border=1></a> -</center> -</table> -<!-- TRAILER --> -</body></html> diff --git a/man/man4/plumber.html b/man/man4/plumber.html deleted file mode 100644 index 83e5943f..00000000 --- a/man/man4/plumber.html +++ /dev/null @@ -1,122 +0,0 @@ -<head> -<title>plumber(4) - Plan 9 from User Space</title> -<meta content="text/html; charset=utf-8" http-equiv=Content-Type> -</head> -<body bgcolor=#ffffff> -<table border=0 cellpadding=0 cellspacing=0 width=100%> -<tr height=10><td> -<tr><td width=20><td> -<tr><td width=20><td><b>PLUMBER(4)</b><td align=right><b>PLUMBER(4)</b> -<tr><td width=20><td colspan=2> - <br> -<p><font size=+1><b>NAME </b></font><br> - -<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> - - plumber – file system for interprocess messaging<br> - -</table> -<p><font size=+1><b>SYNOPSIS </b></font><br> - -<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> - - <tt><font size=+1>plumber</font></tt> [ <tt><font size=+1>−p</font></tt> <i>plumbing</i> ]<br> - -</table> -<p><font size=+1><b>DESCRIPTION </b></font><br> - -<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> - - The <i>plumber</i> is a user-level file server that receives, examines, - rewrites, and dispatches <a href="../man7/plumb.html"><i>plumb</i>(7)</a> messages between programs.

If the alpha channel is present, it - must be at least as deep as any other channel. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The channel string defines the format of the pixels in the file, - and should not be confused with ordering of bytes in the file. - In particular <tt><font size=+1>'r8g8b8'</font></tt> pixels have byte ordering blue, green, - and red within the file. See <a href="../man7/color.html"><i>color</i>(7)</a> for more details of the - pixel format. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - A venerable yet deprecated format replaces the channel string - with a decimal <i>ldepth</i>, which is the base two logarithm of the - number of bits per pixel in the image.

The data, when uncompressed, is laid out in - the usual form. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The data is represented by a string of compression blocks, each - encoding a number of rows of the image’s pixel data. Compression - blocks are at most 6024 bytes long, so that they fit comfortably - in a single 9P message. Since a compression block must encode - a whole number of rows, there is a limit (about 5825 - bytes) to the width of images that may be encoded. Most wide images - are in subfonts, which, at 1 bit per pixel (the usual case for - fonts), can be 46600 pixels wide. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - A compression block begins with two decimal strings of twelve - bytes each. The first number is one more than the <tt><font size=+1>y</font></tt> coordinate - of the last row in the block. The second is the number of bytes - of compressed data in the block, not including the two decimal - strings. This number must not be larger than 6000. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Pixels are encoded using a version of Lempel & Ziv’s sliding window - scheme LZ77, best described in J A Storer & T G Szymanski ‘Data - Compression via Textual Substitution’, JACM 29#4, pp. 928-951. - - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The compression block is a string of variable-length code words - encoding substrings of the pixel data. A code word either gives - the substring directly or indicates that it is a copy of data - occurring previously in the pixel stream. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - In a code word whose first byte has the high-order bit set, the - rest of the byte indicates the length of a substring encoded directly. - Values from 0 to 127 encode lengths from 1 to 128 bytes. Subsequent - bytes are the literal pixel data. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - If the high-order bit is zero, the next 5 bits encode the length - of a substring copied from previous pixels. Values from 0 to 31 - encode lengths from 3 to 34 bytes. The bottom two bits of the - first byte and the 8 bits of the next byte encode an offset backward - from the current position in the pixel data at which the copy - is to be found. Values from 0 to 1023 encode offsets from 1 to - 1024. The encoding may be ‘prescient’, with the length larger - than the offset, which works just fine: the new data is identical - to the data at the given offset, even though the two strings overlap. - - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Some small images, in particular 48×48 face files as used by <i>seemail</i> - (see Plan 9’s <i>faces</i>(1) and <a href="../man7/face.html"><i>face</i>(7)</a>) and 16×16 cursors, can be stored - textually, suitable for inclusion in C source. Each line of text - represents one scan line as a comma-separated sequence of hexadecimal - bytes, shorts, or words in C format. For - cursors, each line defines a pair of bytes. (It takes two images - to define a cursor; each must be stored separately to be processed - by programs such as <a href="../man1/tweak.html"><i>tweak</i>(1)</a>.) Face files of one bit per pixel - are stored as a sequence of shorts, those of larger pixel sizes - as a sequence of longs. Software that reads these files must - deduce the image size from the input; there is no header.

Its behavior - is determined by a plumbing rules file, default <tt><font size=+1>/usr/$user/lib/plumbing</font></tt>, - which defines a set of pattern/action - rules with which to analyze, rewrite, and dispatch received messages. - - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The file is a sequence of rule sets, each of which is a set of - one-line rules called patterns and actions. There must be at least - one pattern and one action in each rule set. (The only exception - is that a rule set may contain nothing but <tt><font size=+1>plumb to</font></tt> rules; such - a rule set declares the named ports but has no other effect.) - A - blank line terminates a rule set.

Unlike in C, the file name is not quoted. - If <i>file</i> is not an absolute path name, or one beginning <tt><font size=+1>./</font></tt> or <tt><font size=+1>../</font></tt>, - <i>file</i> is looked for first in the directory in which the plumber - is executing, and then in <tt><font size=+1>/sys/lib/plumb</font></tt>. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - When a message is received by the <tt><font size=+1>plumber</font></tt>, the rule sets are examined - in order. For each rule set, if the message matches all the patterns - in the rule set, the actions associated with the rule set are - triggered to dispose of the message. If a rule set is triggered, - the rest are ignored for this message. If none is - triggered, the message is discarded (giving a write error to the - sender) unless it has a <tt><font size=+1>dst</font></tt> field that specifies an existing port, - in which case the message is emitted, unchanged, from there. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Patterns and actions all consist of three components: an <i>object</i>, - a <i>verb</i>, and arguments. These are separated by white space on the - line. The arguments may contain quoted strings and variable substitutions, - described below, and in some cases contain multiple words. The - object and verb are single words from a pre- - defined set. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The object in a pattern is the name of an element of the message, - such as <tt><font size=+1>src</font></tt> or <tt><font size=+1>data</font></tt>, or the special case <tt><font size=+1>arg</font></tt>, which refers to - the argument component of the current rule. The object in an action - is always the word <tt><font size=+1>plumb</font></tt>. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The verbs in the pattern rules describe how the objects and arguments - are to be interpreted. Within a rule set, the patterns are evaluated - in sequence; if one fails, the rule set fails. Some verbs are - predicates that check properties of the message; others rewrite - components of the message and implicitly always succeed. - Such rewritings are permanent, so rules that specify them should - be placed after all pattern-matching rules in the rule set.<br> - - <table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> - - <tt><font size=+1>add</font></tt> The object must be <tt><font size=+1>attr</font></tt>.

If, however, the message has an - attribute named <tt><font size=+1>click</font></tt>, that reports that the message was - produced by a mouse click within the text and that the regular - expressions in the rule set should be used to identify what portion - of the data the user intended. Typically, a program such as an - editor will send a white-space delimited block of text containing - the mouse click, using the value of the <tt><font size=+1>click</font></tt> attribute (a - number starting from 0) to indicate where in the textual data - the user pointed. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - When the message has a <tt><font size=+1>click</font></tt> attribute, the <tt><font size=+1>data matches</font></tt> rules - extract the longest leftmost match to the regular expression that - contains or abuts the textual location identified by the <tt><font size=+1>click</font></tt>. - For a sequence of such rules within a given rule set, each regular - expression, evaluated by this specification, must - match the same subset of the data for the rule set to match the - message. For example, here is a pair of patterns that identify - a message whose data contains the name of an existing file with - a conventional ending for an encoded picture file:<br> - - <table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> - - <tt><font size=+1>data matches '[a−zA−Z0−9_–./]+'<br> - data matches '([a−zA−Z0−9_–./]+).(jpe?g|gif|bit|ps|pdf)'<br> - </font></tt> - </table> - The first expression extracts the largest subset of the data around - the click that contains file name characters; the second sees - if it ends with, for example, <tt><font size=+1>.jpeg</font></tt>. If only the second pattern - were present, a piece of text <tt><font size=+1>horse.gift</font></tt> could be misinterpreted - as an image file named <tt><font size=+1>horse.gif</font></tt>. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - If a <tt><font size=+1>click</font></tt> attribute is specified in a message, it will be deleted - by the <tt><font size=+1>plumber</font></tt> before sending the message if the <tt><font size=+1>data matches</font></tt> - rules expand the selection. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The action rules all have the object <tt><font size=+1>plumb</font></tt>. There are only three - verbs for action rules:<br> - - <table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> - - <tt><font size=+1>to</font></tt> The argument is the name of the port to which the message will - be sent. If the message has a destination specified, it must match - the <tt><font size=+1>to</font></tt> port of the rule set or the entire rule set will be skipped. - (This is the only rule that is evaluated out of order.)<br> - <tt><font size=+1>client</font></tt> If no application has the port open, the arguments to a - <tt><font size=+1>plumb start</font></tt> rule specify a shell program to run in response to - the message. The message will be held, with the supposition that - the program will eventually open the port to retrieve it.<br> - <tt><font size=+1>start</font></tt> Like <tt><font size=+1>client</font></tt>, but the message is discarded. Only one <tt><font size=+1>start</font></tt> - or <tt><font size=+1>client</font></tt> rule should be specified in a rule set.<br> - - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - - </table> - The arguments to all rules may contain quoted strings, exactly - as in <a href="../man1/rc.html"><i>rc</i>(1)</a>.

All requests on a connection share the - same fid space; when several clients share a connection, the agent - managing the sharing must arrange that no two clients choose the - same fid. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The fid supplied in an <tt><font size=+1>attach</font></tt> message will be taken by the server - to refer to the root of the served file tree.

This <tt><font size=+1>afid</font></tt> is established - by exchanging <tt><font size=+1>auth</font></tt> messages and subsequently manipulated using - <tt><font size=+1>read</font></tt> and <tt><font size=+1>write</font></tt> messages to exchange authentication information - not defined explicitly by 9P.

Usually, a client maintains a fid - for the root, and navigates by <tt><font size=+1>walks</font></tt> from the root fid. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - A client can send multiple T-messages without waiting for the - corresponding R-messages, but all outstanding T-messages must - specify different tags.

The qid represents the - server’s unique identification for the file being accessed: two - files on the same server hierarchy are the same if and only if - their qids are the same. (The client may have multiple - fids pointing to a single file on a server and hence having a - single qid.) The thirteen-byte qid fields hold a one-byte type, - specifying whether the file is a directory, append-only file, - etc., and two unsigned integers: first the four-byte qid <i>version</i>, - then the eight-byte qid <i>path</i>. The path is an integer unique among - all files - in the hierarchy. If a file is deleted and recreated with the - same name in the same directory, the old and new path components - of the qids should be different. The version is a version number - for a file; typically, it is incremented every time the file is - modified. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - An existing file can be <tt><font size=+1>opened</font></tt>, or a new file may be <tt><font size=+1>created</font></tt> in - the current (directory) file.

In most such cases, the server should generate - an error rather than modify the data to fit, such as by truncating - the file name. The exception is that a long error string in an - <tt><font size=+1>Rerror</font></tt> message should be truncated if necessary, since the string - is only advisory and in some sense arbitrary. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Most programs do not see the 9P protocol directly; on Plan 9, - calls to library routines that access files are translated by - the kernel’s mount driver into 9P messages.<br> - <p><font size=+1><b>Unix </b></font><br> - On Unix, 9P services are posted as Unix domain sockets in a well-known - directory (see <a href="../man3/getns.html"><i>getns</i>(3)</a> and <a href="../man4/9pserve.html"><i>9pserve</i>(4)</a>).
