sockets - how to listen on multiple ports

[Jim Kipp]

Hi
I am writing a simple server to monitor ports. The problem is I don't know
how to make it listen on multiple ports. It creates the first socket,
listens, than accepts and of course the accept call blocks, so it does not
return to create socket for the other ports. I am doing this in windows, so
using 'fcntl' to do non blocking won't work.
Any suggestions? I can paste the code if need be.

Thanks

Under Unix, you would use the select function, or the OO
interface-to-select IO::Select. Hopefully, these work under windows. In
particular, see "perldoc IO::Select" for an example of how to monitor
input from several sockets.
