Cleanup of the application...

Petike · 08-16-2008, 03:09 PM

Hi all,
I am currently learning graphics programming in DirectX (but I want to talk about my problem in general way, so I will not bother you with DirectX details).

So let's say that we must first initialize the DirectX before using it and in the end of the application we must clean it up. So when the program runs normally and nothing obvious happens, the cleanup at the end of the program will run normally and the application will end. So everything is all right, yeah.
Here is the sample:

Code:

int main()
{
    initDirectX();

    .
    .   // Whatever code in application
    .

    cleanup();

    return 0;
}

But what if the program is NOT terminated normally?
For example what when the user press "CTRL+ALT+DEL" in the middle of the program and terminate the program himself? -> the cleanup will be NEVER achieved.

So HERE IS MY QUESTION:
==================================================
Is there any way to perform the cleanup of the application although
the user terminates the application with "CTRL+ALT+DEL" (or where
should I put my "cleanup()" function in the code)?
==================================================

Thanks.

If I'm not mistaken, in case of Ctrl-Alt-Delete Windows will send your program a WM_CLOSE message or such, attempting to close the program in a usual way.

If your program is caught in an infinite loop or such this will not probably work. But if your program gets stuck in an infinite loop, unloading resources is not the biggest problem?
