How do you clear a stringstream variable?

Question

I\'ve tried several things already,

std::stringstream m;
m.empty();
m.clear();

both of which don\'t work.

Answer 1

These do not discard the data in the stringstream in gnu c++

    m.str("");
    m.str() = "";
    m.str(std::string());

The following does empty the stringstream for me:

    m.str().clear();
