enable_hardware_cursor - Man Page

#include <allegro.h>

void enable_hardware_cursor(void);

After calling this function, Allegro will let the operating system draw the mouse cursor instead of doing it itself. This is not possible with all graphics drivers though: you'll need to check the gfx_capabilities flags after calling show_mouse() to see if this works. On some platforms, enabling the hardware cursor causes get_mouse_mickeys() to return only a limited range of values, so you should not call this function if you need mouse  mickeys.
