Hello Vincent, As per what I remember it had been decided that this should be left to the calling program to do rather than make it part of libxcb. If I remember correctly I had an initWSA function as part of my libxcb port and as per recommendations from other developers I had taken it off and we decided that WSA init and cleanup be done in the program using libxcb. Thread should be in archives somewhere. Bye for now <div class="gmail_quote">On Mon, Apr 18, 2011 at 12:26 PM, Vincent Torri <<a href="mailto:vtorri@univ-evry.fr">vtorri@univ-evry.fr</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hey, one need to call WSAStartup() on Windows once (technically speaking, it can be called several times). and for each WSAStartup() call, WSACleanup() must be called. What would be the best way to do that in libxcb ?
