#25961 [Opn]: sem_get with fixed IDC_CREAT flag

ID: 25961 Updated by: iliaa@php.net Reported By: daredevil at rozmova dot if dot ua Status: Open -Bug Type: Semaphore related +Bug Type: Documentation problem Operating System: FreeBSD, cygwin PHP Version: 4.3.3 New Comment: It seems strange that IPC_CREATE flag is always set, but it's removal will break backwards compatibility. The only way I see that this problem could be resolved is by adding another optional argument to the function, which would disable IPC_CREATE flag. Previous Comments: ------------------------------------------------------------------------ [2003-10-23 02:51:32] daredevil at rozmova dot if dot ua Description: ------------ in the sem_get function, according to the source code, semaphore *always* getting with IPC_CREATE flag. That is unnecessary in situations, when I wanna get an existing semaphore, not to create a new one. Also in the Documentation You should mention, that a PHP semaphore is really THREE of them! Because when writing an client-server app (php as a client platform ang C/C++ as a server platform), and a semaphore is created in C++ as semget(key, 1(!), IPC_CREATE | 0666) - I need onle one! When trying to reach it in php sem_get(key) php handles an "ivalid argument exception" because php wanna re-create the semaphore set from 1 to 3. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25961&edit=1
