[Discussion] Proposed interface for files

[erikfrojdh]

Here is a proposed interface for reading files. The actual file would inherit from this and implement (at least) the pure virtual functions.

Overview

• seek/tell sets and gets the position to read from
• read returns a frame
• read_into reads directly into a buffer provided by the user (the user has to be 100% sure that the buffer is large enough)

Did I miss anything essential? (remember it has to work for any type of files) or did I include too much?

Looks good. Would be good also to have write functions
