note 58349 added to ref.sem

Actually, the way to lock a semaphore from C code appears to be: <? struct sembuf semptr[2]; if( (semid = semget(SEM_KEY, PHP_SEM_NEED_NUMBER, 0666 | IPC_CREAT)) < 0 ) { perror("semget"); return 1; } semptr[0].sem_num = 0; semptr[0].sem_op = -1; semptr[0].sem_flg = SEM_UNDO; semptr[1].sem_num = 1; semptr[1].sem_op = 1; semptr[1].sem_flg = SEM_UNDO; if( semop(semid, &semptr[0], 2) < 0 ) { perror("semop"); } ?> PS: Disregard the <? and ?>, it's just for pretty printing... this is C code! ---- Manual Page -- http://www.php.net/manual/en/ref.sem.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+58349 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+58349&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+58349&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+58349&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+58349&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+58349&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+58349&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+58349&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+58349&report=yes Search -- http://master.php.net/manage/user-notes.php
