read position mouse cursor

Hi to all!
I'm a teacher of maths and physics in an italian high school in Milan, Italy.
I need a simple program that read the position of mouse cursor in function of time and write the coordinates in a text file. The time resolution have to be something like 1/10 sec or better (I have to know this parameter in advance). I can do that with a macro in labview but I can't buy that program. This work will be a part of physics lab in my classroom: we want to plot oscillation (in function of time) of a pendulum followed by an optical mouse.
thank you in advance for help!

NAME
exmouse - Getting input from the mouse. Allegro game programming library. SYNOPSIS
#include <allegro.h> Example exmouse DESCRIPTION
This program demonstrates how to get mouse input. The first part of the test retrieves the raw mouse input data and displays it on the screen without using any mouse cursor. When you press a key the standard arrow-like mouse cursor appears. You are not restricted to this shape, and a second key press modifies the cursor to be several concentric colored circles. They are not joined together, so you can still see bits of what's behind when you move the cursor over the printed text message. SEE ALSO
