Not quite trivial, but not deep either. The coordinates are passed in
the LPARAM for the message (see LOWORD and HIWORD). You probably need
to use GetCapture and SetCapture to get all "mouse" input. Sorry, but
my code is just a bit too proprietary for me to share.

If you don't have a graphical interface, how were you using
GetMouseMovePoints? Also (perhaps relevant), I use the same code for
"big" Windows (mouse) and CE (stylus).
