| static pointer allocate( Alloc& a, size_type n );

(1) | (since C++11) |
| static pointer allocate( Alloc& a, size_type n, const_void_pointer hint );
|
(2) | (since C++11) |
Uses the allocator a to allocate n*sizeof(Alloc::value_type) bytes of uninitialized storage.
1) Calls a.allocate(n)
2) Additionally passes memory locality hint
hint. Calls a.allocate(n, hint) if possible. If not possible (e.g. a has no two-argument member function allocate()), calls a.allocate(n)
[edit] Parameters
| a | - | allocator to use |
| n | - | the number of objects to allocate storage for |
| hint | - | pointer to a nearby memory location |
[edit] Return value
The pointer returned by the call to a.allocate(n)
