inline RMemReadStream();

Description

IMPORT_C RMemReadStream(const TAny *aPtr, TInt aLength);

Description

Construct a stream that reads from a pointer of any type.

Parameters

const TAny *aPtr The start address for the area of memory that will be the source of this stream. TInt aLength The length of the area of memory.

See also:

• RMemReadStream::Open(const TAny *,TInt)Open a stream that reads from a pointer of any type.

IMPORT_C void Open(const TAny *aPtr, TInt aLength);

Description

Open a stream that reads from a pointer of any type.

Parameters

const TAny *aPtr The start address for the area of memory that will be the source of this stream. TInt aLength The length of the area of memory.
