[cs631apue] udgramread

Tonight in class the 'udgramread' and 'udgramsend' programs did not work
as expected.  The reason is that I modified the two programs this
afternoon without verifying that my change did what it should have done
-- a common mistake. :-}

I've updated the code with the correction and confirmed it to work as it

$ ./udgramread
socket -> socket
$ ls -l socket

$ ./udgramsend socket
$ fg
--> The sea is calm tonight, the tide is full . . .

Sorry about the mistake earlier.
