note 25836 added to function.ftok

It seems to be the same function as in C : DESCRIPTION The ftok() function returns a key based on path and id that is usable in subsequent calls to msgget(), semget() and shmget(). The path argument must be the pathname of an existing file that the process is able to stat(). The ftok() function will return the same key value for all paths that name the same file, when called with the same id value, and will return different key values when called with different id values or with paths that name different files existing on the same file system at the same time. It is unspecified whether ftok() returns the same key value when called again after the file named by path is removed and recreated with the same name. ... So you give the Path of your critical ressource, and a Id which will allow you to have one or more semaphore on this file. -- http://www.php.net/manual/en/function.ftok.php http://master.php.net/manage/user-notes.php?action=edit+25836 http://master.php.net/manage/user-notes.php?action=delete+25836 http://master.php.net/manage/user-notes.php?action=reject+25836
