msg_get_queue — Create or attach to a message queue
Description
msg_get_queue ( int $key [, int $permissions = 0666 ] ) : SysvMessageQueue|false
msg_get_queue() returns an id that can be used to access the System V message queue with the given key. The first call creates the message queue with the optional permissions. A second call to msg_get_queue() for the same key will return a different message queue identifier, but both identifiers access the same underlying message queue.
Parameters
-
key -
Message queue numeric ID
-
permissions -
Queue permissions. Default to 0666. If the message queue already exists, the
permissionswill be ignored.
Return Values
Returns SysvMessageQueue instance that can be used to access the System V message queue, or false on failure.
