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