Help creating a quote server simulator
I'm designing a quote/ticker simulator using streams that will emulate real-time quotes into my program ( a data pumper, if you will). I'm new to sockets programming, but after reading Beej's guide, and a few others, I think I have the basics, and can setup the basic connection between a client and server. I... 12 Apr 2010 13:39
The way I understand Beejs unix networking that I was kindly told about is that getaddrinfo() is used first and through pointer menipulation over linked lists getaddrinfo() returns what is needed.
