    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

    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

    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
