Say I have a std::stringstream sstr, and i load some string data into it via the << operator. Now I want to clear that data out, and load new data in. How do I go about clearing out a std:stringstream? clear() and flush() dont work, so im stuck.

Did you try sstr.str(""); ?

clear() just resets the streams error flags, shouldnt need that unless fail() returns true.

But since many valid operations may end up setting that flag, it''s worthwhile to clear it.
