inline RBufReadStream();

Description

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

Description

Construct a stream that reads from a dynamic buffer.

Parameters

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

See also:

• RBufReadStream::Open(const CBufBase &,TInt)Open a stream that reads from a dynamic buffer.

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

Description

Open a stream that reads from a dynamic buffer.

Parameters

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