show_mouse(3)                   Allegro manual                   show_mouse(3)



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

SYNOPSIS
       #include <allegro.h>


       void show_mouse(BITMAP *bmp);

DESCRIPTION
       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 cursor.

       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().
