Typedefs
typedef boost::function7< void, const qi::log::LogLevel, const qi::os::timeval, const char *, const char *, const char *, const char *, int >	logFuncHandler
	Boost delegate to log function (verbosity lv, date of log, category, message, file, function, line). e.g.
Enumerations
enum	LogLevel {   silent = 0, fatal, error, warning,   info, verbose, debug }
	Log level verbosity. More...
Functions
QI_API void	init (qi::log::LogLevel verb=qi::log::info, int ctx=0, bool synchronous=true)
	init the logging system (could be avoided)
QI_API void	destroy ()
	stop and flush the logging systemshould be called in the main of program using atexit. for example: atexit(qi::log::destroy) This is useful only for asynchronous log.
QI_API void	log (const qi::log::LogLevel verb, const char *category, const char *msg, const char *file="", const char *fct="", const int line=0)
	Log functionYou should call qiLog* macro.
QI_API const char *	logLevelToString (const qi::log::LogLevel verb)
	Convert log verbosity to char*.
QI_API qi::log::LogLevel	stringToLogLevel (const char *verb)
	Convert string to log verbosity.
QI_API void	setVerbosity (const qi::log::LogLevel lv)
	Set log verbosity.If you don't want any log use silent mode.
QI_API qi::log::LogLevel	verbosity ()
	Get log verbosity.
QI_API void	setContext (int ctx)
	Set log context.Display log context (line, function, file).
QI_API int	context ()
	Get log context.
QI_API void	setSynchronousLog (bool sync)
	Set synchronous logs.
QI_API void	addLogHandler (const std::string &name, qi::log::logFuncHandler fct)
	Add log handler.
QI_API void	removeLogHandler (const std::string &name)
	remove log handler.
