Function Documentation

int bytes_to_decimal	(	unsigned char *	bytes,
		int	n
	)

This function receives n bytes and convert them to an integer.

int variable_time	(	unsigned char *	bytes,
		int *	k
	)

This function receives k bytes and convert them to an integer, according to the sintax of the Variable Length Values presented in the MIDI Specification.

void system_exclusive	(	unsigned char *	bytes,
		int *	k
	)

This function interprets the bytes of 'system exclusive' events.

void meta	(	unsigned char *	bytes,
		int *	k,
		int	delta_time
	)

This function interprets the bytes of 'meta' events.

void midi	(	unsigned char *	bytes,
		int *	k,
		int	type,
		int	track,
		int	delta_time
	)

This function interprets the bytes of 'midi' events.

int load_midi

(

FILE *

input

)

This function receives a MIDI file, reads its bytes, interprets them and fills the table of MIDI events. It also assigns values to some important global variables (like 'n_tracks' and 'ticks_per_beat'). It returns 0 in case of success and returns 1 otherwise.
