Detailed Description

template<class ForwardIterator, class Type = typename std::iterator_traits<ForwardIterator>::value_type>
struct __gnu_cxx::temporary_buffer< ForwardIterator, Type >

This class provides similar behavior and semantics of the standard functions get_temporary_buffer() and return_temporary_buffer(), but encapsulated in a type vaguely resembling a standard container.

By default, a temporary_buffer<Iter> stores space for objects of whatever type the Iter iterator points to. It is constructed from a typical [first,last) range, and provides the begin(), end(), size() functions, as well as requested_size(). For non-trivial types, copies of *first will be used to initialize the storage.

malloc is used to obtain underlying storage.

Like get_temporary_buffer(), not all the requested memory may be available. Ideally, the created buffer will be large enough to hold a copy of [first,last), but if size() is less than requested_size(), then this didn't happen.
