get_midi_length(3alleg4)					  Allegro manual					  get_midi_length(3alleg4)

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. SEE ALSO
