mqueue

Manage message queues (QNX Neutrino)


Note: You must be root to start this manager.

Syntax:

mqueue &

Runs on:

Neutrino

Options:

There are no options for mqueue manager.

Description:

The mqueue manager implements POSIX 1003.1b message queues. When you create a queue, it appears in the pathname space under /dev/mqueue.

The traditional POSIX message queue manager is a resource manager that uses messages to communicate with its clients. You can access it locally or remotely, allowing for network-wide message queues. On a self-hosted Neutrino system, the default sysinit script starts mqueue; for more information, see the Controlling How Neutrino Starts chapter of the Neutrino User's Guide.


Note: Starting with release 6.3.0, procnto manages named semaphores, which mqueue used to do (mqueue still manages named semaphores if it detects that procnto isn't doing so).

For more information, see the Managing POSIX Message Queues technote.
