This API supports the SQL Server 2012 infrastructure and is not intended to be used directly from your code.

Provides an interface that supports reading and writing data to stream objects.

The IStream type exposes the following members.

Methods

  Name Description
Public method Clone Infrastructure. Creates a new stream object with its own seek pointer that references the same bytes as the original stream.
Public method Commit Infrastructure. Ensures that any changes made to a stream object that is open in transacted mode are reflected in the parent storage.
Public method LockRegion Infrastructure. Restricts access to a specified range of bytes in the stream.
Public method RemoteCopyTo Infrastructure. Copies a specified number of bytes from the current seek pointer in the stream to the current seek pointer in another stream.
Public method RemoteRead Infrastructure. Reads a specified number of bytes from the stream object into memory starting at the current seek pointer.
Public method RemoteSeek Infrastructure. Changes the seek pointer to a new location relative to the beginning of the stream, to the end of the stream, or to the current seek pointer.
Public method RemoteWrite Infrastructure. Writes a specified number of bytes into the stream object starting at the current seek pointer.
Public method Revert Infrastructure. Discards all changes that have been made to a transacted stream since the last Commit(UInt32) call.
Public method SetSize Infrastructure. Sets the size of the stream object.
Public method Stat Infrastructure. Retrieves the tagSTATSTG structure for this stream.
Public method UnlockRegion Infrastructure. Removes the access restriction on a range of bytes previously restricted with the LockRegion(_ULARGE_INTEGER, _ULARGE_INTEGER, UInt32) method.
