socket programming

[Caltech News Server]

I think one possiblity is to send along with your string the number of
characters in your string. Then at the receving end, make two recv calls,
one to get the number of chars coming up and a second to retrieve all the
chars. I'm not sure but you may have to continue receiving until you've got
all characters.
