char* smf_decode

(

const smf_t *

smf

)

Returns

Textual representation of the data extracted from MThd header, or NULL, if something goes wrong. Returned string looks like this:

format: 1 (several simultaneous tracks); number of tracks: 4; division: 192 PPQN.

You should free the returned string afterwards, using free(3).

char* smf_event_decode

(

const smf_event_t *

event

)

Returns

Textual representation of the event given, or NULL, if event is unknown. Returned string looks like this:

Note On, channel 1, note F#3, velocity 0

You should free the returned string afterwards, using free(3).

int smf_event_is_metadata

(

const smf_event_t *

event

)

Returns

Nonzero if event is metaevent. You should never send metaevents; they are not really MIDI messages. They carry information like track title, time signature etc.

Definition at line 57 of file smf_decode.c.

int smf_event_is_sysex

(

const smf_event_t *

event

)

Returns

Nonzero if event is SysEx message.

Definition at line 104 of file smf_decode.c.

int smf_event_is_system_common

(

const smf_event_t *

event

)

Returns

Nonzero if event is System Common.

Definition at line 90 of file smf_decode.c.

int smf_event_is_system_realtime

(

const smf_event_t *

event

)

Returns

Nonzero if event is System Realtime.
