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 opera- tion. If this happens the mouse buffering and graphics drawing code will get confused and will leave 'mouse droppings' all over the screen. To pre- vent 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 cur- sor. 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().
