3 | * Message_queues to leave the option of having unnamed message |

4 | * queues at a future date. They are currently not part of the |
---|
5 | * POSIX standard but unnamed message_queues are. This is also |
---|
6 | * the reason for the apparently unnecessary tracking of |
---|
7 | * the process_shared attribute. [In addition to the fact that |
---|
8 | * it would be trivial to add pshared to the mq_attr structure |
---|
9 | * and have process private message queues.] |
