destroy_midi - Destroys a MIDI structure when you are done with it.
Allegro game programming library.
#include <allegro.h>
void destroy_midi(MIDI *midi);
Destroys a MIDI structure when you are done with it. It is safe to call
this even when the MIDI file might be playing, because it checks and
will kill it off if it is active. Use this to avoid memory leaks in
your program.
