    2 questions about winsock 2

    hi, i have 2 questions about winsock2.

    VS's help says that winsock2 is not avaiblable for MFC. does that mean that if I make an mfc dll, i can't use winsock2? or do i just have to #include "Winsock2.h"? and if not, how would I make a dll that uses winsock in vs2008?

    the other question.. if I only have the socket's file descriptor (or "socket descriptor?") how would I get a SOCKET object from that (or a pointer/reference to its socket object)?


    btw, what i'm trying to do is make a dll that mimics Python's select.poll, using WSAPoll, so that I can then use the dll from Python using ctypes, since python doesn't come with select.poll support for windows..just in case anyone has any tips for that. thanks.

    You have to use MFC's CSocket() or CAsyncSocket() class.

    Until you can build a working general purpose reprogrammable computer out of basic components from radio shack, you are not fit to call yourself a programmer in my presence. This is cwhizard, signing off.

    thanks, but the problem is that I need to use WSAPoll specifically, and I think it's only available in Winsock2. and for .dll's in vs2008 I only saw two options, and they were both MFC. there *must* be a way to use winsock2 in a dll...!?
