Detailed Description

SyslogAppender sends LoggingEvents to the local syslog system.

Constructor & Destructor Documentation

SyslogAppender()

log4cpp::SyslogAppender::SyslogAppender	(	const std::string &	name,
		const std::string &	syslogName,
		int	facility = LOG_USER
	)

Instantiate a SyslogAppender with given name and name and facility for syslog.

Note that the C syslog API is process global, so instantion of a second SyslogAppender will 'overwrite' the syslog name of the first.

Parameters

name	The name of the Appender
syslogName	The ident parameter in the openlog(3) call.
facility	The syslog facility to log to. Defaults to LOG_USER.

Member Function Documentation

_append()

virtual void log4cpp::SyslogAppender::_append ( const LoggingEvent &  event )

protectedvirtual

Sends a LoggingEvent to syslog.

Parameters

event

the LoggingEvent to log.

Implements log4cpp::AppenderSkeleton.

close()

virtual void log4cpp::SyslogAppender::close ( )

virtual
