Return a newly allocated block of at least size bytes with alignment.

allocateAligned(
bsls::Types::size_type size,
bsls::Types::size_type alignment) = 0;Return the address of a newly allocated block of memory of at least the specified positive size (in bytes), sufficiently aligned such that the returned address satisfies, for the specified alignment, 0 == (address & (alignment - 1)). If size is 0, a null pointer is returned with no other effect. If the requested number of appropriately aligned bytes cannot be returned, then a bsl::bad_alloc exception is thrown, or in a non-exception build the program is terminated. The behavior is undefined unless alignment is both a multiple of sizeof(void *) and an integral non-negative power of two.
address of the newly allocated block, or a null pointer if size is 0
