Synchronizing clients

Synchronization is quite easy to perform. At the point of the code that you want to synchronize all processes, call:

int DICE_sync ( void );

When a client calls DICE_sync, it communicates with the server, updating synchronous variables (see sections 3.2 and 8), and blocks, waiting for a message. Blocking is done with read(2), so you may need to take care in threaded programs.

Once all clients call DICE_sync, the server broadcasts a message, and they all unblock.
