Thread: How to identify that user has terminated the program

Hi
I am using visual studio 2005 .

The following code works fine if there is a abort internal to the program.

I want to know is there any API or signal by using which I can know that user of the program has abnormally terminated the program.

Case 1: The user clicks the close button of the IDE.

Case 2: The user uses the Stop Debugging button to kill the process.

Code:

void SignalHandler(int signal)
{
	do{  
	printf("Application aborting...\n");
	}while(1);
}

int main()
{
    int i = 100;
typedef void (*SignalHandlerPointer)(int);

 SignalHandlerPointer previousHandler;
 previousHandler = signal(SIGABRT, SignalHandler);
abort();

}
