note 89642 added to function.posix-mkfifo

For non-blocking, fopen'd read access to a "half-connected" pipe (created with /usr/bin/mkfifo, posix_mkfifo, etc.), I just go ahead and do: <?php $fh=fopen($fifo, "r+"); // ensures at least one writer (us) so will be non-blocking stream_set_blocking($fh, false); // prevent fread / fwrite blocking ?> The "r+" allows fopen to return immediately regardless of external writer channel. You then have to use your own conventions to track $fh as a pseudo-read-only resource, since fwrite would technically be permitted as well. I've successfully used this approach on Linux with PHP 4.3.10 and PHP 5.2.4 with both half-connected (no writer yet) and pre-connected (writer already waiting) pipes, polling with stream_select as usual. ---- Server IP: 208.69.120.35 Probable Submitter: 74.199.5.198 ---- Manual Page -- http://www.php.net/manual/en/function.posix-mkfifo.php Edit -- https://master.php.net/note/edit/89642 Del: integrated -- https://master.php.net/note/delete/89642/integrated Del: useless -- https://master.php.net/note/delete/89642/useless Del: bad code -- https://master.php.net/note/delete/89642/bad+code Del: spam -- https://master.php.net/note/delete/89642/spam Del: non-english -- https://master.php.net/note/delete/89642/non-english Del: in docs -- https://master.php.net/note/delete/89642/in+docs Del: other reasons-- https://master.php.net/note/delete/89642 Reject -- https://master.php.net/note/reject/89642 Search -- https://master.php.net/manage/user-notes.php
