man mouse_setxrange (Fonctions bibliothèques) - define the boundaries for the mouse cursor
NAME
mouse_setxrange, mouse_setyrange - define the boundaries for the mouse cursor
SYNOPSIS
#include <vgamouse.h>
void mouse_setxrange(int x1, int x2);
void mouse_setyrange(int y1, int y2);
DESCRIPTION
These two define the boundaries for mouse cursor. x1, x2, y1, and y2 are the coordinates of the left, right, bottom, and top edges of the screen, respectively.
The return values of mouse_getx(3) and mouse_gety(3) will always stay in these boundaries.
For 3d pointer devices, there is actually another interface. See mouse_getposition_6d(3).
