Subject: How to get the Windows handle for a socket

On Windows, I do the following (trying to get a nonblocking socket):

f=Win32API.new("ws2_32", "ioctlsocket", ["l", "l", "l"], 'i')
s=TCPServer.new(15000)
f.call(s.fileno, 2147772030, 1) #FIONBIO

This returns 10038, "Not a socket," instead of 0, "Success."  s.fileno
is 3.  On Windows, sockets are simply handles, which don't need to be
low integers like 3, and usually aren't.

What I need is to get the real handle to the socket.  (Or any other way
to set a socket nonblocking in Windows.)

Also, a way to make TCPSocket.new not block would be nice.  I'm trying
to make a chat program, and it needs to stay responsive, so it uses the
GUI toolkit's functions to register a callback when the socket is
selected for.

Thanks,

"Proprietary standard" is an oxymoron.
