Detailed Description

Tail a single file. Should also use cFileChangeWatch/INotify for long duration waits?

Constructor & Destructor Documentation

◆ cLogFileTail()

GrayLib::cLogFileTail::cLogFileTail	(	cStringF	sFilePath,
		STREAM_POS_t	nPos = `0`
	)

◆ ~cLogFileTail()

GrayLib::cLogFileTail::~cLogFileTail ( )

virtual

Member Function Documentation

◆ get_Name()

cStringF GrayLib::cLogFileTail::get_Name ( ) const

inline

◆ ReadLogFile()

HRESULT GrayLib::cLogFileTail::ReadLogFile	(	cStreamOutput *	pOut,
		size_t	nPollSizeMax
	)

Tail the file out to pOut for a max amount of nPollTimeMax and nPollSizeMax. If the file has been shortened. just reset to beginning. Ignore internal edits to file.

Returns: # of line changes detected.
