- * NOTE: 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.
