Hi,
Sure you just need to have a signal handler in your program.
For instance:
#include <signal.h>
int catch_signal(); /* Prototype function */
int main()
{
.
.
.
/*
* Setup to catch interrupt (^C)
*/
signal(SIGINT, catch_signal);
.
.
} /* END: main() */
int catch_signal()
{
printf("\n\nCleaning up.....\n");
.
.
.
printf("bye!\n\n");
exit(0);
}
You can NOT handle SIGKILL!
Good luck!
