Win32 API analog of sending/catching SIGTERM

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.

Solution

  • 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
