NAME

       get_midi_length - Determines the total playing time of a midi, in seconds. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int get_midi_length(MIDI *midi);

DESCRIPTION

       This function will simulate playing the given MIDI, from start to end, to determine how long it takes to play. After calling this function,
       midi_pos will contain the negative number of beats, and midi_time the length of the midi, in seconds.

       Note that any currently playing midi is stopped when you call this function.  Usually you would call it before play_midi, to get the length
       of the midi to be played, like in this example:

	  length = get_midi_length(my_midi);
	  play_midi(my_midi);
	  do {
	     pos = midi_time;
	     textprintf_ex(screen, font, 0, 0, c, -1, "%d:%02d / %d:%02d
",
		pos / 60, pos % 60, length / 60, length % 60);
	     rest(100);
	  } while(pos <= length);

RETURN VALUE

       Returns the value of midi_time, the length of the midi.
