Detailed Description

NTEventLogAppender is an Appender that sends LoggingEvents to the Windows event log.

Building log4cpp.dsp/log4cppDLL.dsp creates the resource DLL NTEventLogAppender.dll. Do not forget to place this DLL in a directory that is on the PATH of the Windows system. Otherwise, the category and message will not display correctly in Event Viewer.
NB: This class is only available on Win32 platforms.

Constructor & Destructor Documentation

◆ NTEventLogAppender()

log4cpp::NTEventLogAppender::NTEventLogAppender ( const std::string &  name,
const std::string &  sourceName 
)

Instantiate an NTEventLogAppender with given name and source.

Parameters
nameThe name of the Appender
sourceNameThe source name to log

◆ ~NTEventLogAppender()

log4cpp::NTEventLogAppender::~NTEventLogAppender ( )
virtual

Member Function Documentation

◆ _append()

void log4cpp::NTEventLogAppender::_append ( const LoggingEvent event)
protectedvirtual

Sends a LoggingEvent to NT Event log.

Parameters
eventthe LoggingEvent to log.

Implements log4cpp::AppenderSkeleton.

◆ addRegistryInfo()

void log4cpp::NTEventLogAppender::addRegistryInfo ( const char *  source)
protected

◆ close()

void log4cpp::NTEventLogAppender::close ( )
virtual

Release any resources allocated within the appender such as file handles, network connections, etc.

Implements log4cpp::AppenderSkeleton.

◆ getCategory()

WORD log4cpp::NTEventLogAppender::getCategory ( Priority::Value  priority)
protected

Convert log4cpp Priority to an EventLog category.

Each category is backed by a message resource so that proper category names will be displayed in the NT Event Viewer.

◆ getType()

WORD log4cpp::NTEventLogAppender::getType ( Priority::Value  priority)
protected

Convert log4cpp Priority to an EventLog type.

The log4cpp package supports 8 defined priorites, but the NT EventLog only knows 3 event types of interest to us: ERROR, WARNING, and INFO.

◆ open()

void log4cpp::NTEventLogAppender::open ( )
protectedvirtual

◆ regGetKey()

HKEY log4cpp::NTEventLogAppender::regGetKey ( TCHAR *  subkey,
DWORD *  disposition 
)
protected

◆ regSetDword()

void log4cpp::NTEventLogAppender::regSetDword ( HKEY  hkey,
TCHAR *  name,
DWORD  value 
)
protected

◆ regSetString()

void log4cpp::NTEventLogAppender::regSetString ( HKEY  hkey,
TCHAR *  name,
TCHAR *  value 
)
protected

◆ reopen()

bool log4cpp::NTEventLogAppender::reopen ( )
virtual

Calls open() and close()

Reimplemented from log4cpp::AppenderSkeleton.

◆ requiresLayout()

bool log4cpp::NTEventLogAppender::requiresLayout ( ) const
virtual

The NTEventLogAppender does its own Layout.

Returns
false

Implements log4cpp::AppenderSkeleton.

◆ setLayout()

void log4cpp::NTEventLogAppender::setLayout ( Layout layout)
virtual

Set the Layout for this appender.

Parameters
layoutThe layout to use.

Implements log4cpp::AppenderSkeleton.
