Defined in header <memory>
template< class T >
static void destroy( Alloc& a, T* p );
(since C++11)

Calls the destructor of the object pointed to by p. If possible, does so by calling a.destroy(p). If not possible (e.g. a does not have the member function destroy(), then calls the destructor of *p directly, as p->~T().

Contents

Parameters

a - allocator to use for destruction
p - pointer to the object being destroyed

Return value

(none)

Notes

Because this function provides the automatic fall back to direct call to the destructor, the member function destroy() is an optional Allocator requirement since C++11.
