Named pipes are useful for simple IPC messaging. POSIX message queues are more appropriate for complex communication and notification requirements, especially where a server may be doing a lot of ancillary processing. They are both tools for interprocess communication and coordination, and can have multiple readers/writers involved. What the differences are in resource utilization and efficiency, I'm not sure. One important difference is that message queue messages can be prioritized, which pipes cannot do. Pipes are purely FIFO devices, where queues can prioritize traffic in order to process more time-critical events appropriately.Sometimes, real fast is almost as good as real time.
