To return or clear the basic_string object stored in the buffer.
basic_string<char_type> str() const; void str(const basic_string<char_type>&s);
The function str() freezes the buffer then returns a basic_string object.
The function str(const string s) assigns the value of the string `s' to the stringbuf object.
The no argument version returns a basic_string if successful. The function with an argument has no return.
