If you exactly how the data is structured, you may be able to define several 
structures which define the layout of the data, e.g.

align(1) struct Header
{
    uint magic;
    uint version;
    char[100] comments;
}

Or something along those lines, and then read it in with readExact:

Stream s = ...
Header h;
s.readExact(&h, Header.sizeof);

If the format is more complex, it'll probably take a bit more work, but 
that's the general idea.
