I had looked at that before.  I'm not sure whether that project uses 
some sort if IDE or what, but I found the code a tad hard to read due to 
the use of a lot of (what I'm assuming are) temporary variables.  For 
example, lines 3974 through 4145 in scanner.c.

However it did clue me in to using the SANE_FIX() macro to properly get 
values assigned to the variables that I needed to pass to the 
sane_control_option() function.

Thanks for the nudge in the right direction.
