Constructor & Destructor Documentation

RBufReadStream()

RBufReadStream

(

)

[inline]

Constructs an empty read stream object.

Call Open() to prepare the stream for reading.

RBufReadStream(const CBufBase &, TInt)

IMPORT_C	RBufReadStream	(	const CBufBase &	aBuf,
			TInt	aPos = 0
		)

Constructs the RBufReadStream object and opens the stream hosted by the specified dynamic buffer for reading using the Open() method.

RBufReadStream::Open

Parameters

const CBufBase & aBuf	The dynamic buffer that will be the source of this stream.
TInt aPos = 0	The offset within the dynamic buffer where the stream starts.

Member Functions Documentation

Open(const CBufBase &, TInt)

IMPORT_C void	Open	(	const CBufBase &	aBuf,
			TInt	aPos = 0
		)

Prepares the stream hosted by the specified dynamic buffer for reading.

To close the stream and free its resources call Close()

TBufBuf::Set RReadStream::Attach

Parameters

const CBufBase & aBuf	The dynamic buffer that will be the source of this stream.
TInt aPos = 0	The offset within the dynamic buffer where the stream starts.
