Defined in header <memory>
void* align( std::size_t alignment,

             std::size_t size,
             void*& ptr,

             std::size_t& space );
 （C++11 起）
如果它是可能的，以适应size字节对齐成指向的缓冲区长度alignment由ptrspace存储，函数修改ptr指向的第一可能的地址，例如对齐的存储，并降低由用于对准的字节数的space 。如果这是不可能的（缓冲区太小），align一无所有
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.
