Effects: Obtains a pointer to storage sufficient to store up to n adjacent T objects. It is implementation-defined whether over-aligned types are supported ([basic.align]).
Returns: A pair containing the buffer's address and capacity (in the units of sizeof(T)), or a pair of 0 values if no storage can be obtained or if n <= 0.
Effects: Deallocates the buffer to which p points.
Requires: The buffer shall have been previously allocated by get_temporary_buffer.
