Subject: Assn 5:  Window management

---- Reminder mid term exam is Tuesday ---------

(This message is being sent to all CPSC 360 students)

Dealing with the offered/usable window is NOT necessary
nor required for assn 5,  but it will be required for
assn 6.

If you are struggling with assn 5 I recommend that you
DON"T deal with it.

------------------------------------------------------

But if you aren't struggling its a good way to get ahead.

Regardless, when you get around to dealing with it there
is an issue that was not well specified.   The best way
to do this is to add this line to rps_make_header()

       hdr->win   = rpsock->rcvring.slots;

And to add this line to rps_rcvconn, rps_rcvack, AND
rps_rcvcack

   rpsock->offwin = hdr->win;
