You use the access_ok macro to validate a user-space pointer for a given operation.
您可以使用 access_ok宏来验证给定操作的用户空间指针。
You can also test whether a user-space pointer is valid through a call to access_ok.
您也可以通过调用access_ok来测试用户空间指针是否有效。
This function calculates the difference between two jiffies values, and then provides the result to the user through a user-space pointer.
这个函数会计算这两个jiffies值之间的差值，然后通过一个用户空间指针将结果提供给用户。
For the most part, attempts to treat Pointers as integers come out of attempts to optimize, for either space or efficiency, programs that do a lot of pointer handling.
对于大部分情况来说，试图将指针当作整型来处理的做法来源于试图对执行大量指针处理的程序进行优化，这可能是为了空间或效率的需要。
There are several costs to card marking - additional space for the card map, additional work to be done on each pointer store, and additional work to be done at garbage collection time.
卡片标记有几项开销——卡片映射所需的额外空间、对每一个指针存储所做的额外工作，以及在垃圾收集时做的额外工作。
A COM client interacts with a COM object by acquiring a pointer to one of the object's interfaces and invoking methods through that pointer, as if the object resides in the client's address space.
COM的客户程序通过获取指向一个对象接口的一个指针，并通过该指针来调用方法以实现与COM对象之间的互相作用，就好像对象驻留在客户程序的地址空间中一样。
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。
This function accepts a pointer to a user space buffer, a pointer to a kernel buffer, and a length defined in bytes.
该函数接受一个指向用户空间缓冲区的指针、一个指向内存缓冲区的指针、以及一个以字节定义的长度。
You use the access_ok function to check the validity of the pointer in user space that you intend to access.
您可以使用 access_ok函数在您想要访问的用户空间检查指针的有效性。
The __user macro simply tells the compiler (through noderef) that the pointer should not be dereferenced (as it's not meaningful in the current address space).
__user宏简单告诉编译器（通过noderef）不应该解除这个指针的引用（因为在当前地址空间中它是没有意义的）。
The clear_user function is used to zero a block of memory in user space. This function takes a pointer in user space and a size to zero, which is defined in bytes.
clear_user函数被用于将用户空间的内存块清零。
When you take the mouse pointer on top of the pie chart pointing to each database portion, you can see the percentage value that particular space has covered within the pie chart.
如果把鼠标指针放在饼图上面，指向每个数据库部分，就会看到对应的百分数。
Each CUDA context has it's own virtual memory space, therefore you can not use a pointer from one context inside an another context.
每个CUDA上下文都有它自己的虚拟内存空间，因此你不能使用一个指针从一个上下文在另一个上下文。
A frame function can dynamically allocate stack space and can employ a frame pointer.
帧函数可以动态分配堆栈空间并采用帧指针。
Access is provided to the first memory space through a first pointer stored in a subtree entry.
