-
-<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>
-
- <i>Regcomp</i> compiles a regular expression and returns a pointer to
- the generated description. The space is allocated by <a href="../man3/malloc.html"><i>malloc</i>(3)</a>
- and may be released by <i>free</i>. Regular expressions are exactly as
- in <a href="../man7/regexp.html"><i>regexp</i>(7)</a>.
- <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
-
- <i>Regcomplit</i> is like <i>regcomp</i> except that all characters are treated
- literally. <i>Regcompnl</i> is like <i>regcomp</i> except that the <tt><font size=+1>.</font></tt> metacharacter
- matches all characters, including newlines.
- <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
-
- <i>Regexec</i> matches a null-terminated <i>string</i> against the compiled
- regular expression in <i>prog</i>. If it matches, <i>regexec</i> returns <tt><font size=+1>1</font></tt> and
- fills in the array <i>match</i> with character pointers to the substrings
- of <i>string</i> that correspond to the parenthesized subexpressions
- of <i>exp</i>: <tt><font size=+1>match[</font></tt><i>i</i><tt><font size=+1>].sp</font></tt> points to the beginning and
- <tt><font size=+1>match[</font></tt><i>i</i><tt><font size=+1>].ep</font></tt> points just beyond the end of the <i>i</i>th substring. (Subexpression
- <i>i</i> begins at the <i>i</i>th left parenthesis, counting from 1.) Pointers
- in <tt><font size=+1>match[0]</font></tt> pick out the substring that corresponds to the whole
- regular expression. Unused elements of <i>match</i> are filled with zeros.
- Matches involving <tt><font size=+1>*</font></tt>, <tt><font size=+1>+</font></tt>, and <tt><font size=+1>?</font></tt> are
- extended as far as possible. The number of array elements in <i>match</i>
- is given by <i>msize</i>. The structure of elements of <i>match</i> is:<br>
-
- <table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>
-
- <tt><font size=+1>typedef struct {<br>
-
- <table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>
-
- union {<br>
- char *sp;<br>
- Rune *rsp;<br>
- } s;<br>
- union {<br>
- char *ep;<br>
- Rune *rep;<br>
- } e;<br>
-
- </table>
- } Resub;<br>
-
- <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
- </font></tt>
-
- </table>
- If <tt><font size=+1>match[0].s.sp</font></tt> is nonzero on entry, <i>regexec</i> starts matching
- at that point within <i>string</i>. If <tt><font size=+1>match[0].e.ep</font></tt> is nonzero on entry,
- the last character matched is the one preceding that point.
- <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
-
- <i>Regsub</i> places in <i>dest</i> a substitution instance of <i>source</i> in the
- context of the last <i>regexec</i> performed using <i>match</i>. Each instance
- of <tt><font size=+1>\</font></tt><i>n</i>, where <i>n</i> is a digit, is replaced by the string delimited
- by <tt><font size=+1>match[</font></tt><i>n</i><tt><font size=+1>].sp</font></tt> and <tt><font size=+1>match[</font></tt><i>n</i><tt><font size=+1>].ep</font></tt>. Each instance of <tt><font size=+1>&amp;</font></tt> is replaced
- by the string delimited by <tt><font size=+1>match[0].sp</font></tt> and
- <tt><font size=+1>match[0].ep</font></tt>. The substitution will always be null terminated and
- trimmed to fit into dlen bytes.
- <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
-
- <i>Regerror</i>, called whenever an error is detected in <i>regcomp</i>, writes
- the string <i>msg</i> on the standard error file and exits. <i>Regerror</i>
- can be replaced to perform special error processing. If the user
- supplied <i>regerror</i> returns rather than exits, <i>regcomp</i> will return
- 0.
- <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
-
- <i>Rregexec</i> and <i>rregsub</i> are variants of <i>regexec</i> and <i>regsub</i> that use
- strings of <tt><font size=+1>Runes</font></tt> instead of strings of <tt><font size=+1>chars</font></tt>. With these routines,
- the <i>rsp</i> and <i>rep</i> fields of the <i>match</i> array elements should be used.<br>
