[Boost.python] Converting python file object to std::istream.
I am exposing a C++ class to python that takes a reference to a std::istream object and operates on it. It looks something like this: class StreamReader { public: StreamReader(std::istream& strm); private: std::istream& strm_; } I would like to expose this class to python allowing a python client to pass in any python file type object (regular file object, StringIO object, stdin, etc.), as a C++ client would be able to pass any std::istream derived object. Now it seems to me that someone must have encountered this problem before, but I haven't seen any references as to how to make this work. Any ideas on the best way to proceed would be appreciated. thanks, Dan
