Description:
The mqueue manager implements POSIX 1003.1b message queues. It is a resource manager that handles message queue administration (e.g., queue creation and destruction), but because the queues are in kernel space, queue send, receive, and notification do not have message-passing overhead.
When you create a queue, it appears in the pathname space under /dev/mqueue. The /dev/mqueue directory appears as soon as you start mqueue.
