Defined in header <memory>
void* align( std::size_t alignment,              std::size_t size,              void*& ptr,              std::size_t& space );		(ya que C + +11)

Si es posible encajar size bytes de almacenamiento alineado por alignment en el buffer apuntado por ptr con space longitud, la función modifica ptr para que apunte a la primera dirección posible de dicho almacenamiento alineados y disminuye space por el número de bytes utilizado para la alineación . Si no es posible (el búfer es demasiado pequeño), align no hace nada .

Original:

If it is possible to fit size bytes of storage aligned by alignment into the buffer pointed to by ptr with length space, the function modifies ptr to point to the first possible address of such aligned storage and decreases space by the number of bytes used for alignment. If it is impossible (the buffer is too small), align does nothing.
