ISequentialStream interface
Applies to: desktop apps | Metro style apps
The ISequentialStream interface supports simplified sequential access to stream objects. The IStream interface inherits its Read and Write methods from ISequentialStream.
When to implement
You can implement ISequentialStream on an object if you require simple sequential access to a stream object. If you implement IStream, you must provide an implementation of the Read and Write methods from ISequentialStream.
Note Most applications do not implement ISequentialStream as a separate interface, and you are not required to provide it separately even if you provide an IStream implementation. For example, the compound file implementation of structured storage does not succeed on a QueryInterface method for ISequentialStream but it includes the Read and Write methods through the IStream interface pointer.
When to use
Call the methods of the ISequentialStream interface from a container or application to perform sequential read and write operations on data. Most applications call the Read and Write methods through the IStream interface.
Members
The ISequentialStream interface inherits from the IUnknown interface. ISequentialStream also has these types of members:
Methods
The ISequentialStream interface has these methods.
| Method | Description |
|---|---|
| Read |
Reads a specified number of bytes from the stream object into memory starting at the current seek pointer. |
| Write |
Writes a specified number of bytes to the stream object starting at the current seek pointer. |
