Created child process listens on a socket and exits when it receives anything. The main process checks the child PID using kill(pid, 0) with child PID as a parameter. Even when the child has exited this function call returns 0. When I have supplied any PID which hasn't ever existed it's fine and kill(non-existentPID, 0) returns -1. Has anyone experienced something like this? I'm using Cygwin 1.5.5 version(DLL version). Regards, MacNowak P.S. For now I'm using kill(pid, SIGCONT) as a workaround. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
