WSA-Poll

WSA-Poll is a Windows-specific alternative to poll, used for monitoring multiple sockets for readiness in non-blocking network applications. It is commonly utilized in server-side game development to handle multiple client connections efficiently. Unlike select, WSA-Poll eliminates the limitation of FD_SETSIZE, allowing it to scale better for a larger number of connections. However, it is generally less efficient than epoll on Linux due to its linear scanning mechanism. For high-performance game servers on Windows, IOCP (I/O Completion Ports) is often preferred over WSA-Poll.
