clearing a stringstream
Author
is there anyway to clear the buffer of a stringstream?
I''m using one to hold a description string that''s writen to in a serialise method, but I want to be able to change it after a certain point.
any ideas?

std::stringstream stream;

std::stringstream stream;
stream.str("");

I think clear or flush would have worked too.
stringstream::clear() doesn''t clear the buffer, but the stream flags (eof, fail, bad). As such, it is required too.
std::stringstream stream;
stream.clear();
stream.str("");

stream = std::stringstream();

Standard iostreams are not assignable. If they were, your method would reset all the stream''s state (format option, locale, user data...) not just clear the buffer.
Swapping the rdbuf() with a local one isn''t a very good idea either (lifetime issue), nor is dynamic allocation (ha!)
