/*

 *  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.
