Yes, because it simply uses the Python methods .read(), .write() etc. > Is it necessary to explicitly invoke the streambuf object from python? Yes. I could be different and in fact was different in the initial implementation (if you look back in the svn history). But there were a few subtle problems (buffer size, exception handling) and in the end I decided the most obvious and robust approach is to require streambuf(sys.stdout) or ostream(sys.stdout). I think it is safe to re-use the same streambuf, e.g. def foo(): out = ostream(sys.stdout) func1(out) func2(out) which is almost what you want. But I'd avoid "out" as a global because output may get stuck in the buffer and only appear surprisingly in unrelated contexts. Note that buffer_size=1 introduces a noticeable performance penalty.
