Defined in header `<memory>`
static void deallocate ( Alloc & a, pointer p, size_type n ) ;		(since C++11) (constexpr since C++20)

Uses the allocator a to deallocate the storage referenced by p , by calling a. deallocate ( p, n ) .

Parameters

a	-	allocator to use
p	-	pointer to the previously allocated storage
n	-	the number of objects the storage was allocated for

Return value

(none)
