You will also need IStream_Clone, which shlwapi doesn't implement.

You can look at istream.c for inspiration, but please avoid copying it
verbatim with its 2-space indentation and CamelCaseNotation. Try
following the coding style of surrounding code in msi.
You can probably also simplify the code a bit. E.g. you can leave out
parameter validation and code/structure fields that will not be used
