Member Function Documentation

◆ ReadStringLine() [1/2]

HRESULT Gray::cStreamTextReader::ReadStringLine	(	OUT char *	pszBuffer,
		StrLen_t	iSizeMax
	)

overridevirtual

iSizeMax = Maximum number of characters to be copied into pszBuffer (including room for the the terminating '\0' character).
Returns
length of the string read in chars. (includes \r
) (not including null)

Reimplemented from Gray::cStreamInput.

◆ ReadStringLine() [2/2]

HRESULT Gray::cStreamTextReader::ReadStringLine ( OUT const char ** ppszLine )

protected

Read a line of text. like fgets(). Read up until (including) newline character =
= The newline character, if read, is included in the string. like .NET StreamReader.ReadLine

Returns: length of the string read in chars. (includes \r
) (not including null) 0 = EOF (legit end of file). < 0 = other error

◆ ReadX()

virtual HRESULT Gray::cStreamTextReader::ReadX	(	void *	pData,
		size_t	nDataSize
	)

inlineoverrideprotectedvirtual

Implements Gray::cStreamStackInp.

◆ Seek()

STREAM_SEEKRET_t Gray::cStreamTextReader::Seek	(	STREAM_OFFSET_t	iOffset,
		SEEK_ORIGIN_TYPE	eSeekOrigin = `SEEK_Set`
	)

overridevirtual

Disambiguate Seek for cStreamBase to cStreamInput for stupid compiler.

eSeekOrigin = // SEEK_SET ?
Returns
the New position, -1=FAILED

Reimplemented from Gray::cStreamQueue.

◆ WriteX()

virtual HRESULT Gray::cStreamTextReader::WriteX	(	const void *	pData,
		size_t	nDataSize
	)
