detect data on a TCP socket

[peter ho]

Hi! I am new to socket programming. When I open a socket to a TCP server, is there a way to detect data whenever it's coming back? Please help! Thanks

What I/O model does the server utilize? Under a non-blocking I/O model, the server either monitors the socket. Some I/O models such as WSAAsyncSelect utilizes a process message queue to update a thread on socket activity. Kuphryn

Look into the select() api call. You can detect a pending receive either blocking or unblocking in a loop based on the timeout value you specify.
