libbinio provides a set of classes, called binwstream,
biniwstream and binowstream, that can be wrapped around
an already existing stream from the standard or traditional C++
iostream library.
To do this, you just have to pass a pointer to the original stream
object from the iostream library to the constructor of the appropriate
binwstream class. Of course, you have to match an input stream
from the iostream library to an input stream from libbinio and
analogous for the output-only streams. The class framework will
prevent you from mismatching them. You can, however, wrap an
unidirectional binary stream around a bidirectional stream from the
iostream library.
There is one important thing you have to remember: If you plan to wrap
a binary stream around an iostream stream, always open the iostream
stream with the ios::bin mode flag set! This will prevent some
operating systems (namely, MS-DOS and Windows) from doing nasty
implicit interpretation on the streams. This definitly will impose
problems when you try to read or write the binary stream.
All other flags, you set when opening the original iostream stream, can indirectly have effect on the operations you do on the wrapped binary stream.
