SYNOPSIS
#include <allegro.h>

and also before displaying a mouse pointer, playing FLI animations or MIDI music, and using any of the
GUI routines.
RETURN VALUE
Returns zero on success, or a negative number on failure (but you may decide not to check the return
value as this function is very unlikely to fail).
