From: newsham AT lava DOT net (Tim Newsham) Subject: signals from non-cygwin processes? 30 Dec 1997 18:28:11 -0800 Message-ID: Mime-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit To: gnu-win32 AT cygnus DOT com Hi, I would like to be able to send a cygwin process a signal from a non-cygwin process. When one cygwin process wants to signal another it does it with a message as: SendMessage(hwnd, WM_USER, SIGNAL, signo); where hwnd is the hidden window (?) of the target process and SIGNAL is the constant 1 and signo is the signal number to send. So it seems that it should be possible for non-cygwin processes to signal a cygwin process if it can find out the value of hwnd. So my question is: Is there a way one process can find out the value of the hwnd belonging to a cygwin process? What if the first process was the entity that spawned the cygwin process?
