Modify Mouse Coordinates via "Control to Display Gain" ratio

Question

Deal all,

I made an application in C on Linux OS (ubuntu 8.10) to smooth the mouse movement. My application calculates Control to Display gain, which is used to smmoth the motion of mouse cursor.

Is there any Linux API which we can pass this gain to modify the mouse position. As in Windows there is an API as "SetSystemInfo()", which accepts the gain for mouse movement. OR Is there any better way of doing it?

Many Thanks,
