Special Forums IP Networking Packetize data to send it over tcp sockets Post 302908117 by DGPickett on Thursday 3rd of July 2014 04:52:31 PM

TCP is a reliable stream with no packet borders, so you need to write a protocol to run inside it that defines packet size at least, if you need to recover the packets. Otherwise, just treat it like a pipe/FIFO, but bidirectional. The main trick in TCP protocols is to make sure both ends are not just reading or just sending, as that is a lockup. If you have threads or poll/select() controlled I/O then that is less of a problem (you are both reading and writing both ends all the time).
