Re: Problem with select/5 on AF_INET sockets with Windows 7

[Fx]

:)) Paulo, you are right, if it can help. I won’t promise anything, but i can 
at least take a look, sure.

Can you help, and tell me where cans i found some infos:
- What are actually the tools (or info link )to compile under Windows (7,32b my 
office copmuter)
- What are actually the tools (or info link )to compile under Os X (this one is 
really rather a computer, my personnal(s) one(s)).

Dont’ they exists some kinda unit tests ? Prolog coded scenario ?  Or a Jenkins 
like for massive testing ?

Fx (shorter).
