| Name | Description | |
|---|---|---|
![]() | Clone | Creates a new stream object with its own seek pointer that references the same bytes as the original stream. |
![]() | Commit | Ensures that any changes made to a stream object open in transacted mode are reflected in the parent storage. |
![]() | CopyTo | Copies a specified number of bytes from the current seek pointer in the stream to the current seek pointer in another stream. |
![]() | LockRegion | Restricts access to a specified range of bytes in the stream. |
![]() | Read | Reads a specified number of bytes from the stream object into memory starting at the current seek pointer. |
![]() | Revert | Discards all changes that have been made to a transacted stream since the last Commit call. |
![]() | Seek | 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. |
![]() | SetSize | Changes the size of the stream object. |
![]() | Stat | Retrieves the STATSTG structure for this stream. |
![]() | UnlockRegion | Removes the access restriction on a range of bytes previously restricted with LockRegion. |
