msg_get_queue — Create or attach to a message queue
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 perms. 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.
Message queue numeric ID
Queue permissions. Default to 0666. If the message queue already exists, the perms will be ignored.
Returns a resource handle that can be used to access the System V message queue.
