在WinAPI中为控制台应用程序处理窗口关闭事件的最简单方法是什么？

Question

I'm writing a console multi-process application in c++ using WinAPI. So I have the Dispatcher(eg "Parent") and the Client(eg "Child") processes. Both processes are synchronized: they're using semaphors, events, mutexes and the pipe (all of them are standard WinAPI handles). Application stop when the user type the "exit" command. If the user do so, the dispatcher process notifies it's child, and then child releases its resources and makes another before-exit procedures to exit correctly. But there's a thing that bothers me: what will happen if the user press the window "close" button? If so, I should listen to close event and then perform my resource-releasing procedure. What is the easiest way to handle window close event?

Answer 1

编写一个控制台处理程序例程 ，检测CTRL_CLOSE_EVENT（和CTRL_C_EVENT，如果需要），并使用SetConsoleCtrlHandler将处理程序例程添加到您的进程。

Answer 2

It isn't really different from the client process crashing or being terminated through Task Manager. You ought to be resilient to that as well. The ultimate signal you get for that in the parent process is that the client's process handle will be signaled.

Use WaitForMultipleObjects, along with those other handles, to detect this.
