This doesn't make sense. You can always do system("c:/cygwin/bin/kill -HUP
<cygwin_pid>").

Cygwin signals use Windows events under the covers, but there's more to Cygwin signals
than just Windows events. There's no one-to-one mapping. Use "kill".

Thank you Igor!
I know it sounds ugly, but let me go a little more into detail.
I want to do the following:
Start a native Win32 application, let us call it the 'frontend'.
This frontend starts and stops some cygwin applications. Start is no problem, I can do
this with
the Win32's CreateProcess() function. Therefrom I get the applications HANDLE. For
stopping the
application I want to use this HANDLE but I do not want to use the Win32's
TerminateProcess()
function to stop the process because that gives the (cygwin-) applications no time to
save anything.
That is the reason why I am looking for a SIGNAL-sending capability from Win32
applications.
When I listen to your answer I can imagine what to do in my Win32 App.:
1. start the cygwin application via CreateProcess(), get a HANDLE
2. obtain the process' Win32-PID from the obtain HANDLE
3. use the cygwin win_pid to cygwin_pid function
4. use the cygwin kill() function with this pid to send a signal to the cygwin
application
5. wait for the cygwin application to exit
That means to compile the Win32 application with a DLL that does steps 2 to 5.
Can you confirm that this is the way ?
I would be happy to read about a shorter way.
Thank you again
