### Catching SIGALRM and SIGINT Signals
    
    /* signal-catch.c */
    #include <stdio.h>
    #include <stdlib.h>
    #include <string.h>
    #include <signal.h> 
    
    void catcher(int signum)

### Compile and Run

    gcc signal-catch.c -o signal-catch
    ./signal-catch

********************************************************************************
### Test

    ps -A | grep signal-catch
    kill -s SIGALRM 30506 
    kill -s SIGALRM 30506 
    kill -s SIGALRM 30506 
    kill -s SIGINT  30506
