get_midi_length(3)              Allegro manual              get_midi_length(3)

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\n",
                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.
