scare_mouse_area - Man Page

#include <allegro.h>

void scare_mouse_area(int x, int y, int w, int h);

Like scare_mouse(), but will only hide the cursor if it is inside the  specified rectangle. Otherwise the cursor will simply be frozen in place  until you call unscare_mouse(), so it cannot interfere with your drawing.
