Win32 API analog of sending/catching SIGTERM

Question

Under POSIX OS there is signal API that allows to send a signal to process to shut it down with kill and you can catch it with sigaction and do what you need;

However, Win32 is not POSIX system, so:

• How can I handle shutdown events that may come, for example from "End Process" in "Task manager"?
• What is the standard API for sending shutdown signal to Win32 application?

I'm not talking about GUI, I'm talking about TCP/IP server that should be nicely shutdown. that does not run like windows service.

Answer 1

You get a WM_QUIT message on your first created thread.

When you don't handle that, your process is forcibly shutdown.

So just implement a message queue in your first thread, which looks for the WM_QUIT message

Answer 2

MSDNs Unix Code Migration Guide has a chapter about Win32 code conversion and signal handling.
Although Microsoft has decided to archive this brilliant guide, it is very useful.

Three methods are described:
Native signals
Event objects
Messages

Answer 3

May be Windows Power Management from MSDN would be helpful. But it deals with system events rather than per process.

For a process, you would be able to detect termination with WM_CLOSE. You would need to handle windows messages. If it's a console application you would need to install a control handler; take a look at SetConsoleCtrlHandler on MSDN
