You should start by learning communications and networking, there are several books outthere, I'm fond of Mr. Tanenbaum, get a copy of Computer Networks. For TCP/IP itself, read Douglas Comer or Stallings.
However, what you mention in your mail are lwIP functions. Apples and oranges Once you know what a connection oriented protocol is, and get an idea of what a machine to serve that protocol should do, try to think how to make it work in an event driven framework with a small overhead. That is the lwIP raw api. You can read an intro to how to use these functions in the wiki. However, the text assumes you know TCP (it is qiute difficult to do rocket science without knowing about rockets or science, the same applies to networking with microcontrollers). http://lwip.wikia.com/wiki/LwIP_Wiki _______________________________________________ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users
