Added basic_ios abstraction and finished cout/cerr implementation. basic_ios was missing. we should have: ostream -> basic_ios -> ios_base basic_ios's role is very minor for us, it just holds the streambuf where the writes happen. In a real STL it does a bit more, it deals with the numerous flags that can be set on a stream. The ostream implementation is now complete since it can get the streambuf from its base class to perform the 2 ops supported: - flush() - operator<<(char*) The final piece was a concrete implementation of a streambuf to output the strings to stdout or stderr. This is done in a new class stdio_filebuf which wraps a regular stdio.h stream. For cerr we use stderr to build the stdio_filebuf instance that cerr will wrap. Same for cout and stdout.
