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.
