I didn't write it.  It actually came from NCSA's httpd.  This is sample
code they included with the httpd daemon.

Anyway I'm not so sure it's all that bad.  It does exactly the right thing
and I can't think of a better way (in C) to do it.

Yes, I've used SCAN plenty of times.  I already had the above piece of
code for my CGI stuff.  It already did what I wanted.  And honestly SCAN
hasn't seemed that much better (except that it is already part of RPG,
which doesn't matter if I make the getword() function a C module and just
pass stuff to it from RPG).
