Linux I/O multiplexing examples

Overview

This repo contains 3 examples of using system call select, poll and epoll to achieve I/O multiplexing on Linux. Each of the example does the following:

• The main process acts as the server.
• Fork several child processes as clients.
• For each child process/client, create a pipe to communicate with it.
• The client constantly writes to the write side of the pipe.
• The server monitors the read side of each pipe. If there is anything to read, print the client id and the message.

See this post about select v.s. poll v.s. epoll.
