    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();
    
    }

    I think you're looking for SIGTERM

    I thought the code being debugged never gets to see either of these. It's strictly a "do not pass go, do not collect $200" deal.

    Sure, when you're running the program for real, then you may get various messages / signals (depending on your OS) when the program exits by various means.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
