code_converter doesn't support boost::ref( std::istream )

[Richard Smith <richard@…>]

The documentations says that standard iostreams and streambufs model the Device concepts and that they need to be passed by reference via a boost::ref to components expecting a Device. This works in general, but not with the code_converter filter in 1.39. A short test case is:

#include <istream> #include <iostream> #include <boost/ref.hpp> #include <boost/iostreams/code_converter.hpp>

int main() {

namespace io = boost::iostreams; io::code_converter<std::istream> cvt( boost::ref(std::cin) );

}

A trivial patch that fixes this is attached.

Is there any chance of this getting fixed? It is a clear case of the code not matching the documentation, and the provided patch is a trivial two-line change.
