Function Documentation

Log()

void Log	(	LogLevel	level,
		const std::string &	msg,
		const std::string &	file,
		int	lineno
	)

Workhorse of logging.

The log shows not only its content and level, but the file and the line where it was generated as well.

Parameters

level

level of the log, namely

• VERBOSE
• INFO
• WARNING
• ERROR
• FATAL
• UNKNOWN

These names are quite self-explanatory.

Parameters

msg	content of the message
file	the file from which the log is generated
lineno	the line at which the log is generated

Warning

Never call this function directly. Rather, use the LOG macro as follows.

std::string msg = "This is an INFO";
LOG(INFO, msg);
