## Detailed Description

### template\<typename \_ForwardIterator, typename \_Tp\>

class \_\_gnu\_cxx::\_Temporary\_buffer\< \_ForwardIterator, \_Tp \>"This class is used in two places: stl\_algo.h and ext/memory, where it is wrapped as the temporary\_buffer class. See temporary\_buffer docs for more notes.
