FD_READ message

To answer your specific question, if you call recv() and do not receive all of the data ready to be copied, FD_READ will be sent again. You''ll continue to receive an FD_READ on successive calls to recv() until all data in the network buffer has been acknowledged (copied) by your program.

In general, FD_READ is sent:

• When WSAAsyncSelect() is called, if there is data waiting to be received.


• When new data arrives on a socket.


• And in the case discussed above, in which the program has copied a portion of the available data from the network buffer.
