4 * @brief POSIX Message Queues Private Private Support
[5e9b32b]5 *
[21242c2]6 * This include file contains all the private support information for
7 * POSIX Message Queues.
[e49a36c]8 *
[cf301c9]9 * The structure of the routines is identical to that of POSIX
10 * Message_queues to leave the option of having unnamed message
11 * queues at a future date.  They are currently not part of the
12 * POSIX standard but unnamed message_queues are.  This is also
13 * the reason for the apparently unnecessary tracking of
14 * the process_shared attribute.  [In addition to the fact that
15 * it would be trivial to add pshared to the mq_attr structure
16 * and have process private message queues.]
17 *
18 * This code ignores the O_RDONLY/O_WRONLY/O_RDWR flag at open
19 * time.
