[ee122] records

[Merry Choi]

Can anyone illuminate what records are again? And how any of them could not
be full? Would the only reason for recv() return part of a record be because
the buffer exceeded the max 2048 size?

And on that note, the common mistakes states: Separating the records in a
TCP stream. How do we have any control over whether or not send() splits the
records? Or does it have more to do with how we select() clients?
