the 864 on the read call is the number of bytes read. On an open call
it's the file number. On a write it's the bytes written. Etc.

Technically, yes. (In my opinion) although it might be for some other
reason, and not related to the database. Depends on the file id in use
and what that opened to. But probably yes.
