msg_get_queue — Create or attach to a message queue

### Descripción

resource msg_get_queue ( int `$key` [, int `$perms` ] )

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.

### Lista de parámetros

  Message queue numeric ID

`perms`

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

### Valores retornados
