Issues with IRC bot in full C language
29 July, 2009 - 17:53
Hey everyone I am back with a question! woo! haha Well I have been learning network sockets in C and I have tried to create an IRC bot for iadnah's irc server/channel. the problem is that It fails to work properly even though it compiles with out a hitch. when I run the bot it goes straight to command prompt or terminal instead of the bot setting the nick and joining the channel. This bot is just a test bot to test my skills. Once I get it up and running I will design a new permenate bot to take its place.
