A user process cannot directly address memory areas in the address space of another process 一个用户进程不可以直接访问另外一个用户进程的地址空间。
Set statistics xml also produces showplan output , but in xml format , and executes the query 除非一个用户进程终止，否则每个用户都将无限期等待另一个用户释放锁。
Like var , this directory is writeable for user processes , making it a target for dos attacks 类似于/ var ，这个目录对用户进程来说是可写的，使得它成为dos攻击的一个目标。
Each user process has its own private address space , i . e . a collection of memory regions which that process can access 每一个用户进程都有他自己私有的地址空间，也就是可以被那个进程访问的内存集合的区域。
Permission which the user process must possess for the object in order to carry out an operation on the object ( i . e . to retrieve a file ) 系统为执行一种对象操作(如检索一个文件)时,用户进程必须具有完成该作业的许可。
All unix - like systems support user processes ; each process has its own separate memory area , normally untouchable by other processes 所有类- unix系统都支持用户进程；每个进程都有自己的内存空间（其他进程通常无法访问） 。
It also denotes the initialization of kernel data structures , the creation of some user processes , and the transfer of control to one of them 同时，它也代表了初始化内核数据结构、创建用户进程以及将管制权交由这些进程中的其中一个。
Tmpfs itself can t and shouldn t be killed , since it is part of the kernel and not a user process , and there s no easy way for the kernel to find out which process is filling up the tmpfs filesystem Tmpfs本身不能（也不应该）被终止，因为它是内核的一部分而非一个用户进程，而且也没有容易的方法可以让内核找出是那个进程占满了tmpfs文件系统。
Then the article introduces the design and realization of user level monitor module and kernel level monitor module detailedly , including how to realize the system clipboard monitor , the file motion control , file print job interdiction , and the directory share monitor in system ’ s user level , how to realize the process accessing filter , the process privilege control , the file encryption and decryption in system ’ s kernel level 本文详细给出了用户层监控模块和内核层监控模块的设计和实现,包括如何在操作系统用户层实现系统剪贴板监控、文件移动控制、共享目录监控、文件打印阻断等,如何在内核层实现进程访问过滤、用户进程权限控制、文件透明加解密功能。
