       show_mouse - Tells Allegro to display a mouse pointer on the screen.


       #include <allegro.h>

       void show_mouse(BITMAP *bmp);


       Tells  Allegro  to display a mouse pointer on the screen. This will only work if the timer
       module has been installed. The mouse pointer will be  drawn  onto  the  specified  bitmap,
       which  should  normally be `screen' (see later for information about bitmaps). To hide the
       mouse pointer, call show_mouse(NULL).

       Warning: if you draw anything onto the screen  while  the  pointer  is  visible,  a  mouse
       movement  interrupt  could  occur in the middle of your drawing operation. If this happens
       the mouse buffering and graphics drawing code will get  confused  and  will  leave  'mouse
       droppings' all over the screen. To prevent this, you must make sure you turn off the mouse
       pointer whenever you draw onto the screen. This is not needed if you are using a  hardware

       Note:  you  must not be showing a mouse pointer on a bitmap at the time that the bitmap is
       destroyed with destroy_bitmap(), e.g. call show_mouse(NULL); before destroying the bitmap.
       This does not apply to `screen' since you never destroy `screen' with destroy_bitmap().
