Bug #16771 Updated: posix_mkfifo() not properly documented

ID: 16771 Updated by: mfischer@php.net -Summary: posix_mkfifo does weird stuff with mode Reported By: sean@caedmon.net Status: Open -Bug Type: POSIX related +Bug Type: Documentation problem Operating System: Linux 2.2.x (Debian) PHP Version: 4.0CVS-2002-04-23 New Comment: This is a user error. First, only the mode without the quotes INCLUDING the leading zero (because it actually needs to be octal). Second, the actual permission the fifo gets created under also depends on your umask (which is likely to be something like 0022). If you change your umask to 0000 and use 0666 it will work. I'll reclassify this as a documentation problem because it's not really documented. Previous Comments: ------------------------------------------------------------------------ [2002-04-23 18:01:13] sean@caedmon.net Partially true (I tried it without the quotes before I updated from cvs today): posix_mkfifo('./FORK_FIFO', 666); now gives: prw-r--r-- 1 sean sean 0 Apr 23 18:00 FORK_FIFO better, but still not correct.

You need to remove the quotes from around 0666. ------------------------------------------------------------------------ [2002-04-23 17:47:49] sean@caedmon.net posix_mkfifo('./FORK_FIFO', '0666'); // read&write by everyone yeilds: p-w---x--T 1 sean sean 0 Apr 23 17:47 FORK_FIFO ? it SHOULD yeild: prw-rw-rw- The only way for me to get rw, it seems, is with '900', which gives: prw----r-T 1 sean sean 0 Apr 23 17:48 FORK_FIFO (note: I don't even know what T is..) It's messed up, to say the least. S ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=16771&edit=1
