ISequentialStream : IUnknown

OLE DB Programmer's Reference

ISequentialStream is a simplified version of IStream that provides strictly sequential stream access to BLOB data. This class behaves as if it were the strict ancestor of IStream. In particular, any object that implements IStream can choose to identify itself as ISequentialStream because the first two slots in the IStream vtable and the definition of those methods exactly matches the vtable and methods of ISequentialStream.

Method	Description
ISequentialStream::Read	Reads a specified number of bytes from the stream.
ISequentialStream::Write	Writes a specified number of bytes to the stream.
