I just read Sikora's Article on Asynchronous Sockets, this is in regards to the definition of the FD_WRITE event. I am attempting to build from scratch a network for a game engine I'm working on. I want to use UDP sockets and WSAEventSelect. For purposes of sending small packets (<100 bytes) could the send() buffer size be resized such that FD_WRITE is signaled more often. Also, would there be any serious performance drawbacks if the send() buffer was resized each send?

The Forum FAQ cautions against using Windows async sockets. They are basically a hack to make writing simple web browsing type applications in MFC a little easier. The right thing to do on Windows is usually to use select() in your main thread, or if you want to be multi-threaded, use IOCP (overlapped I/O with I/O completion ports).
