Due:  Oct 20th

The goal is to make two programs.

1) Server:  
   Example:  ./server /region1 Love 2 /region2 Hate 3 /region3 "Sugar is sweet" 1 
   Set up N shared memory regions
   Copies the data to the region
   Sets the count to the number
   When all regions are used ... exit
   
2) Client
   Example:  /client /region1
   Maps the named region
   Wait for data to become available no more than 1 second
   Decrements the count
   Print the data
   Quit
   
   
Question:  Why does this code not work for the client?
     int ans = sem_getvalue(...)
     if ans >= 0
         sem_wait(....)

Question:  How does the server know when all the regions are used?

Bonus extra credit:
    If you can cause the server to exit without busy waiting .. +10%.
    But only the first turn-in with each method gets the bonus!

Bonus extra credit:
    If you can make it impossible for the client to access data
    before the server has copied it, and even before the server has
    set up the semaphores, +10%.
    But only the first turn-in with each method gets the bonus!
