Detailed Description

Demonstrates cross-platform monitoring of both socket events and console I/O.

This example creates a simple TCP server that listens on port 12345 for incoming connections and monitors console input for commands. The example is designed to run on both Windows and POSIX systems, using platform-specific mechanisms:

• On POSIX systems, the select() system call is used to monitor both the server socket and the standard input (STDIN_FILENO).
• On Windows, Winsock’s select() function monitors the server socket, while _kbhit() is used in a polling loop to check for console input.

Typing "quit" at the console terminates the server loop.

Note

For Windows, Winsock must be initialized before any socket functions are used, and cleaned up upon termination.
