use str member function.

#include <sstream>

main()
{
std::stringstream sstr;
sstr << "hello";
sstr.str("");
}

Thanks,

No, you can't. clear() clears the iostate flags. str("") makes it empty.

It sure sounds like that's what it should do, doesn't it? Too bad it
really only clears some flags. str("") is the way to reset the string.
