This project allows up to 4 users to play Blackjack. The users can be on different machines, only the IP address and port number of the running server program needs to be known.

To compile everything type at the command prompt:

make

To start the server with a port number 2001 type:

./server 2001

To start a client to connect to the server above type:

./client 127.0.0.1 2001

Up to 4 clients can be started. If the time the server allows for input from the users is too short, it can be increased by modifying the following variables in the file 'common.h':

#define MAX_WAIT_RCV 5 #define MAX_WAIT_GAME 30

The first one allows maximum 5 seconds for client input, and the second one for maximum 30 seconds for the server to wait for players to connect.

After that the server spawns a new process 'dealer' which plays against the players, and when it's done the server continues to listen for new connections for a new game.

The project implements everything that's in the requirements, I believe not a single thing is missing. One small limitation is that if a player waits for too long and then chooses "STAND", his client program will hang forever because he's been disconnected by the dealer, so now he needs to hit Ctrl-C to kill his client program. In all other cases the sockets use a timeout, and if they don't receive the required data they return with an error which the program handles gracefully. The "STAND" feature could also be made to wait for limited time only, but in this case the dealer would need to send periodical "WAIT" messages to all clients which are in "STAND" mode, until all clients are finished HIT-ting.
