I think my process does not share the same environment or what ? if someone got an idea about this ?, I may use another solution before going through a socket solution... thanks gilles -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
