static int last_event_pulses ( const smf_track_t * track )

static

Returns ->time_pulses of last event on the given track, or 0, if track is empty.

void maybe_add_to_tempo_map ( smf_event_t * event )

Definition at line 125 of file smf_tempo.c.

static smf_tempo_t* new_tempo	(	smf_t *	smf,
		size_t	pulses
	)

static

If there is tempo starting at "pulses" already, return it. Otherwise, allocate new one, fill it with values from previous one (or default ones, if there is no previous one) and attach it to "smf".

smf_tempo_t* smf_get_tempo_by_pulses	(	const smf_t *	smf,
		size_t	pulses
	)

Return last tempo (i.e. tempo with greatest time_pulses) that happens before "pulses".

Definition at line 269 of file smf_tempo.c.

smf_tempo_t* smf_get_tempo_by_seconds	(	const smf_t *	smf,
		double	seconds

void smf_track_add_event_delta_pulses	(	smf_track_t *	track,
		smf_event_t *	event,
		uint32_t	delta
	)

Adds event to the track at the time "pulses" clocks from the previous event in this track. The remaining two time fields will be computed automatically based on the third argument and current tempo map. Note that ->delta_pulses is computed by smf.c:smf_track_add_event, not here.

void smf_track_add_event_pulses	(	smf_track_t *	track,
		smf_event_t *	event,
		size_t	pulses
	)

Adds event to the track at the time "pulses" clocks from the start of song. The remaining two time fields will be computed automatically based on the third argument and current tempo map.

Definition at line 418 of file smf_tempo.c.

void smf_track_add_event_seconds	(	smf_track_t *	track,
		smf_event_t *	event,
		double	seconds
	)

Adds event to the track at the time "seconds" seconds from the start of song. The remaining two time fields will be computed automatically based on the third argument and current tempo map.
