With recent changes to Android, simple files are an endangered species and we have to rely on file descriptors. My c++ is rudimentary at best, but if I follow the docs and code to open a file descriptor I'd need to use:

LibRaw::open_datastream

I'd pass in an extension of LibRaw_abstract_datastream that would very closely resemble the existing:

LibRaw_file_datastream and LibRaw_bigfile_datastream but for a FILE*.

And I'd replicate the logic to choose which stream that exists in LibRaw::open_file before calling LibRaw::open_datastream.

Does this sound logical?
