How do you redirect a standard stream of a C++ routine wrapped with SWIG and exposed to Python?

Question

Is it possible to control the standard streams of C++ code in python? The code is wrapped with SWIG and then exposed to Python where I call one of its functions.

I am getting all kinds of unwanted messages coming from C++ code and I want to suppress them either by not using the output stream or by redirecting it to a bit bucket, e.g. devnull from the os module.

I think the best way is to implement a simple function/method in C or C++ of your extension to redirect the stdout output, see dup for example, I think it will work fine.
