## Detailed Description

POSIX Message Queues.

This file contains the definitions related to POSIX Message Queues.

The structure of the routines is identical to that of POSIX Message_queues to leave the option of having unnamed message queues at a future date. They are currently not part of the POSIX standard but unnamed message_queues are. This is also the reason for the apparently unnecessary tracking of the process_shared attribute. [In addition to the fact that it would be trivial to add pshared to the mq_attr structure and have process private message queues.]

This code ignores the O_RDONLY/O_WRONLY/O_RDWR flag at open time.
