It means you want to say "ClosePoly();"--you ALWAYS must use ()'s in a C
function call, even if there are no arguments.

Bzzzzt.  Wrong answer.  There's no need to lock the handle, as it's being
used quite safely.

Now, I'm a bit confused by all the pointer math, but the water
rodent could save itself a lot of work by reading up on using []
with pointers.  A judicious declaration of "res" could hide a lot
of the complexity. (Yes, the large aquatic rat said it was a
beginner, and I'm not flaming; just suggesting...)
