This only works reliably with Cygwin processes. There's $ /bin/kill -f <PID> to call the Win32 function TerminateProcess(pid) on a non-Cygwin process or an unresponsive Cygwin process.As I noted, it was not unique to control-C. In any case, unfortunate to hear that Cygwin will not address this issue. kill -f is clearly not desirable for doing a clean shutdown of a process.
Cygwin can't introduce Unix-like shutdown mechanisms (like the handling a non-fatal signal) into non-Cygwin processes which have no concept of that. It makes no sense. The Windows way to try to try to obtain a clean shutdown is to send a message to a window handle (WM_CLOSE or WM_QUIT or whatever); then if that fails, TerminateProcess rudely. kill shouldn't try to translate signals to window handle messages; it makes no sense. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
