Description

Constructs an empty write stream object.

Call Open() to prepare a stream for writing.

RDesWriteStream(TDes8& aDes);

Description

Constructs the object and prepares a stream, to be hosted by the specified descriptor, for writing using the Open() function.

Parameters

TDes8& aDes The descriptor hosting the stream.

See also:

• RDesWriteStream::Open()

void Open(TDes8& aDes);

Description

Prepares a stream for writing.

When streaming takes place, any existing data in the descriptor will be replaced. Note that the maximum length of the descriptor must be big enough to accommodate the expected streamed data, otherwise the subsequent streaming operation will leave with KErrOverFlow.

A subsequent call to CommitL() sets the length of the descriptor.

Parameters

TDes8& aDes The descriptor hosting the stream.
