I/O Question

I need to find a way to determine whether data is available, for reading, on a socket connection, without blocking a thread. The equivalent of select() or poll() would do the trick. I don't need to get the information for all open files, as you can in select and poll, so a way to find out if there is data available on a single socket (or handle) is sufficient.
