Non-blocking sockets

[damlui]

Hi,

I use activePerl, 5.8.0 built, on Windows 2000 SP3, when I try to make non-blocking sockets with:

fcntl($socket, F_SETFL(), O_NONBLOCK())

I receive the following error:

"Your vendor has not defined Fcntl macro F_SETFL, user at test.pl line 56"

Is there currently any way to get non-blocking sockets on Windows?

I would very much appreciate some assistance with this?

Thanks, Luigi.
