Function Documentation

void mlt_log	(	void *	service,
		int	level,
		const char *	fmt,
			...
	)

Send the specified message to the log if the level is less than or equal to the current logging level.

By default, all logging messages are sent to stderr. This behavior can be altered by setting a different mlt_vlog callback function.

Parameters:

service	An optional pointer to a `mlt_service_s`.
level	The importance level of the message, lower values signifying higher importance.
fmt	The format string (printf-compatible) that specifies how subsequent arguments are converted to output.

See also:: mlt_vlog

int mlt_log_get_level ( void )

void mlt_log_set_callback ( void(*)(void *, int, const char *, va_list) )

void mlt_log_set_level ( int )

void mlt_vlog	(	void *	service,
		int	level,
		const char *	fmt,
		va_list
	)
