What that means is that for each Node, you've really got a location pointer within the complete XML document you handed off to XPathEvaluator.

这意味着，对于每个Node，您实际上获得了传递给XPathEvaluator的完整X ML文档中的一个位置指针。

Conversely, if your program has a fault (for example, using a bad pointer) at some location in memory, you can look for the source line that is closest to the memory address.

相反，如果您的程序在内存中某个位置存在错误(例如，使用了一个错误指针)，那么可以查找最接近该内存地址的源代码行。

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。

Well, it turns out on most computers an address of the location and memory, aka a pointer, is itself 32 bits.

好的，它是一个计算机内存地址,或者说一个指针，占32位。

We have a pointer to the location in memory that contains the actual value, which itself might be a bunch of pointers, and we have a pointer to the actual-- sorry, a pointer the value and we have a pointer to the next element in the list. All right?

包含实际值的地址,可能实际值,也是一系列指针,这里还有指向实际，抱歉，指向下一个元素的指针,我们来整理下？
