POSIX Message Queues

Why

Roughly similar functionality to System V message queues (msgget(2), msgsnd(2), msgrcv(2), etc.).

• API:

  mq_open(2)
  mq_send(2)
  mq_receive(2)
  mq_close(2)
  mq_unlink(2)
  mq_setattr(2), mq_getattr(2) (set/get queue attributes)
  and more...

• Messages boundaries are preserved (like System V messages).
  
  
• Messages have priorities (like System V messages).
