Linux 是一个源码开放的操作系统,无论是普通用户还是企业用户都可以编写自己的内核代码,再加上对标准内核的裁剪从而制作出适合自己的操作系统。目前有很多中低端用户使用的网络设备的操作系统是从标准 Linux 改进而来的,这也说明了有越来越多的人正在加入到 Linux 内核开发团体中。
一个或多个内核模块的实现并不能满足一般 Linux 系统软件的需要,因为内核的局限性太大,如不能在终端上打印,不能做大延时的处理等等。当我们需要做这些的时候,就需要将在内核态采集到的数据传送到用户态的一个或多个进程中进行处理。这样,内核态与用户空间进程通信的方法就显得尤为重要。在 Linux 的内核发行版本中没有对该类通信方法的详细介绍,也没有其他文章对此进行总结,所以本文将列举几种内核态与用户态进程通信的方法并详细分析它们的实现和适用环境。

-Linux is an open-source operating system, both ordinary users or enterprises, users can prepare their core code, coupled with the standard kernel cutting thereby making up their own operating system. There are a lot of low-end users of the network equipment from the standard operating system Linux is improving from the This also shows that the more and more people are added to the Linux kernel development groups. One or more modules and the realization of general Linux can not satisfy the needs of system software, because the core is too restrictive, such as the terminal can print, can not handle the b

completion of the following non
完成ls的如下功能
不带参数的ls:列出当前目录下的非隐藏(文件和目录名不以.开头)的文件和目录
ls -a:列出当前目录下的所有文件和目录
ls -l:以长列表形式列出当前目录下的非隐藏的文件和目录。每个文件或目录只要求列出如下信息:类型与权限、文件名、链接数、用户ID、组ID、字节大小、块数
ls 路径名:如果路径名代表一个存在的文件则显示该文件,否则提示出错;如果路径名字代表一个存在的目录则列出该目录中的文件
列出文件名和目录名时,要求可执行文件最后加上一个*号,目录名最后加上一个/号。
所提供的路径名可以包含“.”,“..”,“~”等特殊目录-completion of the following non-functional parameters of ls : listed in the current directory-hidden (files and directories were not. Beginning) of files and directories ls-a : listed in the current directory of all files and directories ls-l : in the long list of current directory listed under the non-hidden possession of files and directories. Each file or directory only asked to list the following information : the type and competence, file name, number of links, the user ID and group ID, byte size, a few blocks ls path : If a path representatives of the document showed documents suggest otherwise error; If representatives of a path name the presence of the directory lists the directory lists the

Nucleus PLUS实时操作系统是很好的
Nucleus PLUS是美国著名RTOS厂商ATI公司(Accelerated Tedmology lnc) 在嵌入式实
时多任务操作系统Nucleus基础上,为实时嵌入式应用而设计的一个抢先式多任务操作系统内核。其95%的代码是用ANSI C写成的,非常便于移植并支持大多数类型的处理器 Nucleus PLUS是一组c函数库,应用程序代码与核心函数连接在一起,生成一个目标代码,下载到目标板的RAM 中或直接烧录到目标板的ROM 中执行。在典型的目标环境中,Nucleus PLUS核心代码区一般不超过20K字节大小。-Nucleus PLUS RTOS is well-known American manufacturers ATI Corporation (Accelera ted Tedmology lnc) in Embedded Real-time Operating System Nucleus multi-task basis, for real-time embedded applications designed to pre-empt a multi-tasking operating system kernel. Its 95% of the code is written in ANSI C, very easy transplantation and to support most types of processors Nucleus PLUS is a function of the group c, Application code and linked to the core function, generating an object code, downloaded to the target board RAM or direct copying to the target board ROM implementation. In a typical target environment, Nucleus PLUS core code is generally not exceed 20 K byte size.

将需要公开的接口用一个句柄类封装起来,调用者只通过封装的句柄类来调用实现, 这样,将调用与实现隔离开来,或者说只让调用看到它所需要看到的接口。这样的话,只要 保证接口不变,那么实现代码的中要添加一些变量,函数,将不会影响到调用者。-will require an open interface with a handle Packaging category, called only by the Packaging category to handle Call, which would call and to achieve separation, or call only need to see it to see the interface. So, as long as the guarantee the same interface, then the realization of the code necessary to add some variables, function and will not affect the person to call.
