msg_get_queue — Create or attach to a message queue

说明

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.

参数

key

Message queue numeric ID

permissions

Queue permissions. Default to 0666. If the message queue already exists, the permissions will be ignored.

返回值

Returns SysvMessageQueue instance that can be used to access the System V message queue, 或者在失败时返回 false.

更新日志
