NAME
midi_loop_start, midi_loop_end - Loop start and end points, set by play_looped_midi(). Allegro game programming library.
SYNOPSIS
#include <allegro.h>
extern long midi_loop_start;
extern long midi_loop_end;
DESCRIPTION
The loop start and end points, set by the play_looped_midi() function.
These may safely be altered while the music is playing, but you should be
sure they are always set to sensible values (start < end). If you are
changing them both at the same time, make sure to alter them in the right
order in case a MIDI interrupt happens to occur in between your two
writes! Setting these values to -1 represents the start and end of the
file respectively.
