log_sink_trad()

int log_sink_trad	(	void *	instance,
		log_line *	ll
	)

services: log sinks: basic logging ("classic error-log") Will write timestamp, label, thread-ID, and message to stderr/file.

If you should not be able to specify a label, one will be generated for you from the line's priority field.

Parameters

instance	instance handle
ll	the log line to write

Return values

int	number of added fields, if any

log_sink_trad_parse_log_line()

log_service_error log_sink_trad_parse_log_line	(	const char *	line_start,
		size_t	line_length
	)

Parse a single line in the traditional error log.

Parameters

line_start	pointer to the beginning of the line ('2' of the ISO-date)
line_length	length of the line

Return values

LOG_SERVICE_ARGUMENT_TOO_LONG	Token too long for its field
LOG_SERVICE_PARSE_ERROR	No more spaces in line, cannot find expected end of token, or input otherwise malformed
LOG_SERVICE_SUCCESS	Event added to ring-buffer

parse_trad_field()

ssize_t parse_trad_field	(	const char *	parse_from,
		const char **	token_end,
		const char *	buf_end
	)

Find the end of the current field (' ')

Parameters

parse_from	start of the token
token_end	where to store the address of the delimiter found
buf_end	end of the input line

Return values

-1	delimiter not found, "parsing" failed
>=0	length of token
