The file streaming APIs only work on Palm databases that have been created
on the device as file streams. The format is undocumented, but it basically
consists of a database with the file stream attribute set in its header, and
a series of 4K blocks as database records, the blocks acting as file
sectors. I doubt that you could easily read an arbitrary database as a file
stream -- you could probably open a DB and then checksum all of the database
blocks for your purpose, however.
