The <i>inc</i> function is - called each time a new pointer is added to the map; similarly, - <i>dec</i> is called on each pointer left in the map when it is being - freed. Typically these functions maintain reference counts. - New entries are added to the map by calling <i>insertkey</i>, which will - return the previous value associated with the given <i>key</i>, or zero - if there was no previous value. <i>Caninsertkey</i> is like <i>insertkey</i> - but only inserts <i>val</i> if there is no current mapping. It returns - 1 if <i>val</i> was inserted, 0 otherwise. <i>Lookupkey</i> returns the pointer - associated with <i>key</i>, or zero if there is no such pointer. <i>Deletekey</i> - removes the entry for <i>id</i> from the map, returning the associated - pointer, if any. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Concurrent access to <tt><font size=+1>Intmap</font></tt>s is safe, moderated via a <tt><font size=+1>QLock</font></tt> stored - in the <tt><font size=+1>Intmap</font></tt> structure. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - In anticipation of the storage of reference-counted structures, - an increment function <i>inc</i> may be specified at map creation time. - <i>Lookupkey</i> calls <i>inc</i> (if non-zero) on pointers before returning - them. If the reference count adjustments were left to the caller - (and thus not protected by the lock), it would be possible to - accidentally reclaim a structure if, for example, it was deleted - from the map and its reference count decremented between the return - of <i>insertkey</i> and the external increment. <i>Insertkey</i> and <i>caninsertkey</i> - do <i>not</i> call <i>inc</i> when inserting <i>val</i> into the map, nor do <i>insertkey</i> - or <i>deletekey</i> call <i>inc</i> when returning old map entries. - The rationale is that calling an insertion function transfers - responsibility for the reference to the map, and responsibility - is given back via the return value of <i>deletekey</i> or the next <i>insertkey</i>. - - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <tt><font size=+1>Intmap</font></tt>s are used by the 9P library to implement <tt><font size=+1>Fidpool</font></tt>s and <tt><font size=+1>Reqpool</font></tt>s.<br> - -</table> -<p><font size=+1><b>SOURCE </b></font><br> - -<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> - - <tt><font size=+1>/usr/local/plan9/src/lib9p/intmap.c<br> - </font></tt> -</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="../man3/9p.html"><i>9p</i>(3)</a>, <a href="../man3/9p-fid.html"><i>9p-fid</i>(3)</a><br> - -</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> |
