some versions of C have a non standard delay() function otherwise you can use functions in <time.h>, e.g.

    clock_t  clock_start;                         /* holds clock start time */
    clock_start = clock(); 
    while (((clock() - clock_start) / CLOCKS_PER_SEC) < 3)
        /* delay 3 seconds*/ ;

clock() returns the number of clock ticks since the program started and the while() loop waits until 3 seconds has elapsed, see
