You must be root to start this manager. |
mqueue &
Neutrino
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).
