How can I handle console closing in a Windows CE?

Question

I have a Win32 C++ console application running in Window CE 6.0 that contains a number of continuously running threads. Occasionally there is a need to stop the application, and I would like that to happen in a controlled manner. One method of doing this would be to simply monitor the console window, and if it closes then stop the process. Unfortunately SetConsoleCtrlHandler does not appear to be part of the Win32 api for Windows CE 6.0. Does anyone know how I can detect that the console is closing in a Win32 C++ program running in CE?

Thanks,

I got this working on Windows Embedded Compact 7. The Ctrl+C and the "window closed" events are both catched.

1. Create a Win32 event.
2. Pass that event to DeviceIoControl() using the IOCTL_CONSOLE_SETCONTROLCEVENT, and given the console handle (eg, _fileno(stdout)). That event will be signaled when Ctrl+C is typed, or the console window is closed.
3. Create a thread that waits on the Win32 event becoming signaled, and when it becomes so, calls your Ctrl+C handler or performs your cleanup, and probably exits the program.

Notice that IOCTL_CONSOLE_SETCONTROLCHANDLER has been deprecated and DeviceIoControl() fails when it is given that IOCTL code.

You can watch for Ctrl-C by calling DeviceIoControl with IOCTL_CONSOLE_SETCONTROLCHANDLER . Use _fileno (stdout) for the hDevice parameter.

I don't think there's any way to get notified for any other "close" mechanism.
