C 函数实现 

//字节交换: https://msdn.microsoft.com/zh-cn/library/e8cxb8tk.aspx
void _swab(
   char *src,
   char *dest,
   int n 
);

//返回堆中分配的存储块大小: https://msdn.microsoft.com/zh-cn/library/bb384617.aspx
size_t _msize(
   void *memblock,
   size_t alignment,
   size_t offset
);

//为纯虚函数调用设置处理程序: https://msdn.microsoft.com/zh-cn/library/t296ys27.aspx
_purecall_handler _set_purecall_handler( 
   _purecall_handler function
);

//文件和流关联: https://msdn.microsoft.com/zh-cn/library/dye30d82.aspx
FILE *_fdopen(  
   int fd,
   const char *mode 
);
FILE *_wfdopen( 
   int fd,
   const wchar_t *mode 
);
