I have a doubt...

If i have a program with the habilit to create various threads to 
connect to a site via socket (same or different sites), I need to use 
WSAStartup in every one of them or on the main program?

The help says that is possible to call them many times, since the 
WSAClenup be called same number of times...

But my question is: It's necessary? Or on time (on the mais thread), is ok?

Thanks :)

It doesn't really matter, as WinSock is reference counted.  Calling
WSAStartup() and WSACleanup() in each thread will not hurt anything.
Only the first call to WSAStartup() and the last call to WSACleanup()
are important.  The rest are just adjusting the reference count.
