Function ConnectToChatServer

netcon/mtclient/chat_api.cpp:123–270

Return codes: -2 Already connected -1 Failed to connect 0 Connecting 1 Connected Call it once with the server IP address, and it will return immediately with 0. Keep calling it until it returns something other than 0 note: the nickname may be changed if someone with that name already exists (Scourge1 for instance)
