It sounds like what you want to do is write and read a 32KB *record*. Since you created a *stream* socket, the data you send will arrive as a stream of bytes and it's up to you to put it together as a record. > The server calls the recv() function, which returns with 4360 bytes received. > The client has to call the recv() function once again to get the remaining > 15640 bytes of the segment. In my opinion this behaviour is not correct. It may not be the functionality you want, but it is the correct behavior.
