Sys V message queues provide priority, so that a particular queue recipient can be specified and can get messages “aimed” at it. With no contention. Queue readers can access any message as well depending on the mtype value in
msgrcv(). POSIX message queues are a little different. Generally you can employ Sys V queues without having to worry about locking resources. Sys V semaphores queues and shared memory do have some downsides as well. Like the fact that they are kernel persistent.Try
