log_output_buf()

int log_output_buf	(	char *	buf,
		int	buf_len,
		struct log_target *	target,
		unsigned int	subsys,
		unsigned int	level,
		const char *	file,
		int	line,
		int	cont,
		const char *	format,

main output formatting function for log lines.

Parameters

[out]	buf	caller-allocated output buffer for the generated string
[in]	buf_len	number of bytes available in buf
[in]	target	log target for which the string is to be formatted
[in]	subsys	Log sub-system number
[in]	level	Log level
[in]	file	name of source code file generating the log
[in]	line	line source code line number within 'file' generating the log
[in]	cont	is this a continuation (true) or not (false)
[in]	format	format string
[in]	ap	variable argument list for format

Returns

number of bytes written to out
