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.

回答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

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

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
