Manage message queues (QNX Neutrino)
|You must be root to start this manager.|
There are no options for the mqueue manager.
The mqueue manager implements POSIX 1003.1b message queues. When you create a queue, it appears in the pathname space under /dev/mqueue.
|The /dev/mqueue directory doesn't appear until you actually create a queue.|
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.
|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.
