Write a program called snooze that takes a single command-line argument, calls the snooze function from Problem 8.5 with this argument, and then terminates. Write your program so that the user can interrupt the snooze function by typing Ctrl+C at the keyboard. For example:

Problem 8.5

Write a wrapper function for sleep, called wakeup, with the following interface:

unsigned int wakeup(unsigned int secs);

The wakeup function behaves exactly as the sleep function, except that it prints a message describing when the process actually woke up:

Woke up at 4 secs.

linux>./snooze 5 CTRL+C Slept for 3 of 5 secs. linux> User hits Crtl+C after 3 seconds
