> My question is if it wouldn't be more advantageous to create some
wrapper which would take the all necessary inputs including compression
type and do the necessary switches and format specific things.
Agreed.
In practical terms, there are only two distinct cases: uncompressed (where
the size of the data read or written matches the size of the data stored
in the file) and compressed (where the sizes differ). Everything else is
just options.
