Return Value Description


The stream was not opened with GENERIC_WRITE.


The hStream parameter is set to NULL or equal to INVALID_HANDLE_VALUE.


The database from which the stream object was opened had its seek position changed. To prevent this, open a stream, perform the operations, and then close the stream before doing anything else in the parent database.


To set the size of a stream, you must have specified the GENERIC_WRITE flag when opening the stream with CeOpenStream. The size is based on the entire stream and is not relative to the current seek position.

The stream is increased or truncated as required.

To save changes to a stream with this function, call the CeStreamSaveChanges (EDB) function.
