The part I am having difficulty understanding is that on my client program, I loop and call the write 5 different times, on the server, I loop and call the read

As we saw above, once a connection is established, both ends can use read and write to send information to the other end, and the details of the information passed back You also can't control whether TCP coalesces outgoing writes into one segment.

Socket Write Error Ftp Notice that the client needs to know the port number of the server, but it does not need to know its own port number.

This should be set to 5, the maximum size permitted by most systems. If data is 100 bytes in length, datasize will be "100". You can implement a poor man's version of it by read()ing one character at a time until you hit the end-of-line character, for receiving lines of unknown length. http://smartphpstatistics.com/error-writing/charon-10-net-error-writing-to-socket-invalid-argument.html share|improve this answer answered Dec 5 '12 at 22:40 hmjd 88.8k8115178 Correct, though not as ASCII text, instead as raw binary data. –fotg Dec 5 '12 at 23:40
