To access the third field, you would specify register X as the base pointer and12 as the offset. 要访问第三个域,我们需要指定寄存器X作为指针,12作为偏移量。
So, using base-pointer addressing, you would specify register X as the base pointer and8 as the offset. 因此,使用基指针寻址模式,我们可以指定寄存器X作为基指针,8作为偏移量。
Notice how like our recursive programs, the definition of a linked list also contains a base case & in this case, the NULL pointer. 注意,与我们的递归程序非常类似,链表的定义也包括一个基线条件&在这里是NULL指针。
In this paper, T-st index is proposed, it is improved base on T-tree index, the successor and tail pointer are added, and the corresponding algorithm is designed, the ability of range searching, inserting, and deletion are all improved. 本文针对T树索引进行了改进,在原有的节点结构中加入后继指针和尾指针,提出了T-st树索引,设计了相应的算法,使范围查询、插入和删除等方面的性能有较大提高。
Called to determine the base address of a structure whose type is known when the caller has a pointer to a field inside such a structure. 调用该宏计算出已知类型、已有一个域(成员)的指针的结构体的基地址。
