RMemWriteStream();

Description

Constructs an empty write stream object.

Call Open() to prepare a stream for writing.

RMemWriteStream(TAny* aPtr,TInt aMaxLength);

Description

Constructs the object and prepares a stream, to be hosted in the specified plain memory location, for writing using the Open() function.

Parameters

TAny* aPtr A pointer to the memory location. TInt aMaxLength The maximum length of memory available.

void Open(TAny* aPtr,TInt aMaxLength);

Description

Prepares a stream for writing.

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

Parameters

TAny* aPtr A pointer to the memory location. TInt aMaxLength The maximum length of memory available.
