Set Mouse Position with GLUT?

Is it possible to set the mouse cursor position with GLUT?


Use glutWarpPointer( int x , int y );


I thought version 3 was the last version but after I have read about this function I take a look at the header file and saw that there is already version 4 declared.
My question is: are the functions, like glutWarpPointer, anywhere described or do I have to play around with these functions and see for myself how they work? (okay, the source would be another solution but I’m not sure if this is easier for me).
The last specification is for version 3, or did I miss something?
