Capture mouse movement

[JenniferHu]

I am using GLUT lib to do programming on Windows XP. I know there is a function 'glutMotionFunc' can catch mouse movement, but it just can catch the movement when some button is holding.

Is there someone know how I can capture the mouse movement without holding anying button?

You mean like this glut function:

glutPassiveMotionFunc( func )
