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, eg devnull from the os module.

我认为最好的方法是在扩展的C或C ++中实现一个简单的函数/方法来重定向stdout输出，例如，请参见dup ，我认为它将很好地工作。
