Is the change to use 'FILE *' actually progress?
I'd have thought that the randomly aligned read/lseek system calls
that this allows to happen are not desirable for anything that
isn't a true file.

I'd also suggest that the sizeof's should be applied to the
actual type of the variable being read/written, not arbitrarily
'long' or 'int', and this probably ought to be some fixed size type.
