Attempt to open the SMF file for reading and writing.

Currently SMF is always read/write.

int Evoral::SMF< Time >::read_event	(	uint32_t *	delta_t,

	)		const

protected

Read an event from the current position in file.

File position MUST be at the beginning of a delta time, or this will die very messily. ev.buffer must be of size ev.size, and large enough for the event. The returned event will have it's time field set to it's delta time, in SMF tempo-based ticks, using the rate given by ppqn() (it is the caller's responsibility to calculate a real time).

size should be the capacity of buf. If it is not large enough, buf will be freed and a new buffer allocated in its place, the size of which will be placed in size.

Returns event length (including status byte) on success, 0 if event was skipped (eg a meta event), or -1 on EOF (or end of track).

		uint32_t *	size,

	)		const

Read an event from the current position in file.

File position MUST be at the beginning of a delta time, or this will die very messily. ev.buffer must be of size ev.size, and large enough for the event. The returned event will have it's time field set to it's delta time, in SMF tempo-based ticks, using the rate given by ppqn() (it is the caller's responsibility to calculate a real time).

buf must be a pointer to a buffer allocated with malloc, or a pointer to NULL. size must be the capacity of buf. If it is not large enough, buf will be reallocated and *size will be set to the new size of buf.

if the event is a meta-event and is an Evoral Note ID, then note_id will be set to the value of the NoteID; otherwise, meta-events will set note_id to -1.

Returns: event length (including status byte) on success, 0 if event was a meta event, or -1 on EOF (or end of track).
