Detailed Description

Logger is a logger that allows priority based logging with minimal impact on performance and minimal configuration requirements.

Use the environment variable BASE_LOG_LEVEL to define the requested logging level, e.g.:

export BASE_LOG_LEVEL="WARN"

A library designer can decide using the BASE_LOG_xxx flag at compile time which log level should be available.

So switch the output stream (for example logging into a file) the following can be used:

 BASE_LOG_CONFIGURE(priority,ostream)

Member Function Documentation

configure()

void base::logging::Logger::configure	(	Priority	priority,
		FILE *	outputStream
	)

Configure logger - this is for the library developer so he can set a maximum log level, which cannot be further limited to higher log priorities via setting BASE_LOG_LEVEL.

If no previous configuration is given, no output logging will be done

log()

void base::logging::Logger::log	(	Priority	priority,
		const char *	function,
		const char *	filename,
		int	line,
		const char *	name_space,
		const char *	format,
			...
	)		const

Logs a message with a given priority, can be used with printf style format

Parameters

priority	priority level
ns	namespace to be used
filename	Filename
line	Linenumber
format	printf like format string
...	variable argument list

logBuffer()

void base::logging::Logger::logBuffer	(	Priority	priority,
		const char *	function,
		const char *	file,
		int	line,
		const char *	name_space,
		const char *	buffer
	)		const

used by log(...) logs the text contained in buffer.
