Detailed Description¶

template<class _ForwardIterator, class _Tp = typename std::iterator_traits<_ForwardIterator>::value_type>struct __gnu_cxx::temporary_buffer< _ForwardIterator, _Tp >¶

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. Definition at line 184 of file ext/memory.
