The iostreams Adapter Classes
The Streams package has four adapter classes that implement the iostreams streambuf interface:
RWStreambufToCharOutputStream, which implements the iostreams
streambuf interface and forwards to an Advanced Tools Module narrow character output stream
RWStreambufFromCharInputStream, which implements the iostreams
streambuf interface and forwards to an Advanced Tools Module narrow character input stream
The iostreams adapter classes support both the Standard (as described in the C++ standard) and classic iostreams libraries.
