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.

Member Function Documentation

void log4cpp::NTEventLogAppender::_append (const LoggingEvent &event) [protected], [virtual]

Sends a LoggingEvent to NT Event log.

Parameters:

event the LoggingEvent to log.

Implements log4cpp::AppenderSkeleton.

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

void log4cpp::NTEventLogAppender::close () [virtual]

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

Implements log4cpp::AppenderSkeleton.

WORD log4cpp::NTEventLogAppender::getCategory (Priority::Valuepriority) [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.

WORD log4cpp::NTEventLogAppender::getType (Priority::Valuepriority) [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.

void log4cpp::NTEventLogAppender::open () [protected], [virtual]

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

void log4cpp::NTEventLogAppender::regSetString (HKEYhkey, TCHAR *name, TCHAR *value) [protected]

bool log4cpp::NTEventLogAppender::reopen () [virtual]

Calls open() and close()

Reimplemented from log4cpp::AppenderSkeleton.

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

The NTEventLogAppender does its own Layout.
