Detailed Description

Main logging framework header.

Function Documentation

const char const char std::string LogHexDump	(	const unsigned char *	data,
		size_t	len
	)

Convert a sequence of bytes to its textual representation ("hex dump").

Parameters

data	Pointer to the byte sequence to print.
len	Number of bytes to print.

std::vector<std::unique_ptr<LogSink> > g_log_sinks

extern

The set of log sink objects logtools knows about.

When a log message is printed, it is sent to every sink in this list for filtering and display.
