The final item in the stack frame is a pointer to the previous stack frame, often called the back pointer.
堆栈帧中的最后一个条目是一个指向前一堆栈帧的指针，通常被称为后向指针（back pointer）。
Next, the current stack frame pointer is stored as the back pointer for the next stack frame, even though you haven't established the stack frame yet (this is done through negative offsets).
接下来，当前堆栈框架指针会被存储为指向下一个堆栈框架的后向指针，虽然尚未建立堆栈框架(这是通过负的偏移量实现的)。
So, in this function, we are using the back chain pointer, the link register save area, and one local variable.
所以，在这个函数中，我们使用了回链指针、链接寄存器保存区和一个本地变量。
You could even just use a single pointer and write data back into the buffer you got it from, although this might be a nuisance to program for on the other end.
您甚至只需要使用一个指针并将数据写回到读取数据所使用的缓冲区中即可，不过这对于另外一端的编程来说可能有些麻烦。
Each stack frame holds a pointer to the previous stack frame (called the back chain pointer), as well as a space for return addresses for when it calls other functions.
每个堆栈框架都有一个指向前一个堆栈框架的指针(称为回链指针)，还有一个当它调用其他函数时用于存放返回地址的空间。
Back to the API: the PPE can pass a single pointer into the program, so multiple arguments have to be bundled up. My solution is this.
现在回到API上来：PPE只能向程序传递一个指针，因此多个参数必须要捆绑在一起传递。
So, the code loops back, points to the proper top pointer (which was changed because of Thread b), invokes CAS, and is done with pushing 20 into the stack.
因此，代码回到循环的开头，指向正确的top指针(线程b修改后的)，调用CAS，把20压入堆栈后结束。
Then, when they pass the pointer back via free , we simply back up a few memory bytes to find this structure again.
然后，当通过free将该指针传递回来时，我们只需要倒退几个内存字节就可以再次找到这个结构。
The only thing we have to do to free memory is to take the pointer we're given, back up sizeof (struct mem_control_block) bytes, and mark it as available. Here is the code for that.
为了释放内存，我们必须要做的惟一一件事情就是，获得我们给出的指针，回退size of (struct mem_control_block)个字节，并将其标记为可用的。
Increments the row pointer for the next virtual user or, if the end of the file is reached, go back to the beginning of the file and reset the pointer to 1.
为下一位虚拟用户增加行指针或者，如果已经到达文件的末尾，就回到这个文件的起始，使指针重新回到1。
For simplicity, you should have the row pointer always wrap back to the beginning if the end of the file is reached.
为了简单起见，如果已经到达了文件的末端，您应该使这个行指针回到开始。
It hinges on information flowing in two directions, both from the diagram to your eye, but also back from your brain through the mouse pointer to the live diagram.
它取决于两个方向流入的信息，既从图表进入您的眼睛，也通过鼠标指针从您的大脑到达实况图。
After the function has been completed, the return pointer is used to go back to the original location and the program can continue.
当完成该函数之后，使用返回指针回到原来的位置并继续程序。
The next line, C3, takes the pointer in eax and stores it back into the instance reference at memory location 049388C8.
下一行代码，C3，获取 eax中的指针并将其存储回内存位置为 049388C8的实例引用。
It does whatever initialization is required for the module, if any, but most crucially, it also passes a pointer to the method table back to Python.
初始化函数将完成模块所要求的所有初始化操作，但更重要的是，它还把一个指向方法表的指针传回给Python。
Clicking the Pointer Mode button (F9) will switch the Wireframe pane back to Pointer Mode.
单击指针模式按钮(F9键)将切换线框窗格回指针模式。
If the application wants to subclass a window from this ID, it news up the appropriate object and returns the new pointer back to the window.
如果程序想要根据ID为一个窗口生成子类，新建一个适当的对象并把新指针返回给窗口。
And this is not surprising given Siemens long history of co-operation dating back to 1872, when the company delivered China's first pointer telegraph.
这并不奇怪，因为西门子与中国的合作历史可以追溯到1872年，其时西门子为中国交付了第一个指针电报。
Clients of COM objects discover whether a service is available by requesting an interface that provides that service and getting back an interface pointer, or not.
COM对象的客户端通过对提供服务的接口发出请求并取回接口指针来发现服务是否可用。
It is used to cast a pointer type to a wide enough integral type and back to the original pointer type.
用于把指针类型转换到整形以及转回到指针类型。
When using a pointer, hold the pointer in the hand closest to the visual aid to avoid turning your back to the audience.
当你使用指示棒时，要拿在靠屏幕侧的手里，以避免背对听众。
It was back and forth until Wafer's 3-pointer made it 49-45 and gave Houston an opening late in the half.
比分一直交替直到半场快结束时瓦弗尔命中三分将比分变为49-45，帮助火箭稍微拉开比分。
