Detailed Description

This class abstracts the operating system dependent error logging facility.

To send messages to the system error log, the PSYSTEMLOG macro should be used.

Constructor & Destructor Documentation

PSystemLog::PSystemLog

(

Level

level = NumLogLevels

)

Create a system log stream.

Parameters

level

only messages at this level or higher (smaller) will be logged

PSystemLog::~PSystemLog ( )

inline

Destroy the string stream, deleting the stream buffer.

Member Function Documentation

static PSystemLogTarget& PSystemLog::GetTarget ( )

static

Get the current target/destination for system logging.

Referenced by PServiceProcess::GetLogLevel().

PSystemLog::P_DECLARE_ENUM_EX	(	Level	,
		NumLogLevels	,
		StdError	,
		-	1,
		Fatal	,
		Error	,
		Warning	,
		Info	,
		Debug	,
		Debug2	,
		Debug3	,
		Debug4	,

	)

define the different error log levels

Parameters

1	Log from standard error stream

static void PSystemLog::SetTarget ( PSystemLogTarget *  target, bool  autoDelete = true  )

static

Set the current target/destination for system logging.

Parameters

target	New target/destination for logging.
autoDelete	Indicate target is to be deleted when no longer in use.
