Detailed Description

Client/server logic.

Date

2003-12-02

This containes item logic for client/server. It doesn't contain the actual commands that send the data, but does contain the logic for what items should be sent.

MAXITEMLEN

#define MAXITEMLEN   300

This is the maximum number of bytes we expect any one item to take up.

Function Documentation

add_object_to_socklist()

static void add_object_to_socklist ( socket_struct *  ns, SockList *  sl, object *  head  )

static

Used in the send_look to put object head into SockList sl for socket ns.

Need socket to know if we need to send animation of face to the client.
