Description

Under Linux a message queue

Used for interprocess communication, there are 4 routines, you can achieve


1. queue is a list of messages with a specific format, stored in memory by the message queue identifier.
2. message queue allows one or more process writes to it and read the message.
3. pipes and named pipes communication data is first in first out basis.
4. random query Message Queuing can implement a message, information does not necessarily have to be read in FIFO order, or message type read. more advantages than FIFO.

At present there are two main types of message queues: POSIX message queues and system v message queues, the system v message queue currently being used. System v message queue with the kernel, only in the kernel or manually deleted, the message queue will be deleted
