using signal handler for ctrl-c - need help on infinite loops

I am using signal handler for ctrl-c signal. i.e whenever ctrl-c signal is generated instead of exiting the application I do some action.

Let us suppose if my application hangs due to while(1) loop (any error condition) is it possible for me to exit application only in that case?

ex:

void handle()
 {
     /*do some action*/
     ----
     ----
     ---
 
     if ( while(1) detected)
     {
     exit(0);
     }
 }
 
 
 main()
 {
     struct sigaction myhandle; 
     myhandle.sa_handler = handle;
     sigemptyset(&myhandle.sa_mask);
     myhandle.sa_flags = 0;
     sigaction(SIGINT, &myhandle, NULL);
 
    while(1);
 }
 

Thanks
