What did the program print out and please describe what is happening? What is the signal() system call doing?

#include #include #include #include void signalHandler (int); int main() { signal (SIGINT, signalHandler); printf ("wait. "); pause(); return 0; } void signalHandler (int sigNum) { printf ("interrupt recieved. "); sleep (1); printf ("out of here. "); exit(0); }
