I am working on a client for a game, in Perl/Tk. My goal, and reasoning for using Perl/Tk, is to have it as portable as possible.

In the application, I need to read from sockets in a non-blocking fashion. On unix, setting $socket->blocking(0); works like a charm. It doesn't seem to work like that on Windows (running ActivePerl - is there a better solution?).

So, I must do it the 'brute force' method and use fcntl to set non-blocking mode. Yet, when I try to use fcntl on Windows, it tells me "fcntl is not implemented at ..." then quoting the line number on the file it is called.

I tried using POSIX and trying to use the fcntl in POSIX .. to the same problem.

Is fcntl implemented on Windows? Otherwise, is there another solution to set the $socket to non-blocking mode?
