note 100762 added to function.fopen

In other comments it has been noted that fopen hangs when opening any fifo which is not actively being written to. It has also been noted that it is possible to prevent this behaviour by performing an fopen with the "r+" flags such that PHP keeps a handle open to the fifo itself. I hereby document that using the "r+" flag on a pipe under Linux (Slackware 13.0 (i486) and PHP 5.2.14) will render PHP unable to read data waiting to be written to the pipe by any other process. As far as I can tell "r+" is not a valid (read: useful) set of flags for fifo pipes. ---- Server IP: 192.41.42.26 Probable Submitter: 134.82.231.44 ---- Manual Page -- http://www.php.net/manual/en/function.fopen.php Edit -- https://master.php.net/note/edit/100762 Del: integrated -- https://master.php.net/note/delete/100762/integrated Del: useless -- https://master.php.net/note/delete/100762/useless Del: bad code -- https://master.php.net/note/delete/100762/bad+code Del: spam -- https://master.php.net/note/delete/100762/spam Del: non-english -- https://master.php.net/note/delete/100762/non-english Del: in docs -- https://master.php.net/note/delete/100762/in+docs Del: other reasons-- https://master.php.net/note/delete/100762 Reject -- https://master.php.net/note/reject/100762 Search -- https://master.php.net/manage/user-notes.php
