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

Uses the allocatora to deallocate the storage referenced byp, by callinga.deallocate(p, n).

[edit]Parameters

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

[edit]Return value

(none)

allocate [static]	allocates uninitialized storage using the allocator (public static member function)[edit]
