UNIX中的相关介绍ioctl函数 ioctl函数是I/O操作的杂物箱。不能用本章中其他函数表示的I/O操作通常都能用ioctl 表示。终端I/O是ioctl的最大使用方面（第18章将介绍POSIX.1已经用一些新函数代替ioctl 进行终端I/O操作）。 ioctl函数只是Single UNIX Specification标准的一个扩展，以便处理STREAMS设备[Rago 1993]。但是，UNIX系统实现用它进行很多杂项设备操作。有些实现甚至将它扩展到用于普通文件。 我们所示的原型对应于POSIX....
已经有一个摄像头驱动，为了增加功能，准备用ioctl实现。 驱动里，fcap_ioctl函数用switch 根据cmd 来调用相应的功能实现函数。在应用软件里，用ioctl(fd,cmd,...)来调用。 在头文件 linux/videodev.h里，增加cmd的定义，用的是#define cmd ('v',30,struct ...) cmd是自己定义的命令表示 但是编译的时候就是报在应用软件程序里，cmd未定义。。。。。。。 刚接触Linux驱动，请各位大侠指教
Sorry that I can not input Chinese at this machine!! I wanna get the pid name by calling ioctl function using PIOCPSINFO Sign!But this symbol cannot find it! I search my /usr/include directory by greping "PIOCPSINFO" but I cannot find this kind of define! my machine is Redhat 9.0 and my kernel is 2.4.20-8 Is that because redhat9 delete this defination?

http://www.lightbird.net/py-by-example/ Python自带的Tutorial看了没什么收获，还是没上手。可以看看这个，我觉得不错。
Browsing other peoples’ code is a great way to learn new things about a language or framework. I never made it to the Django docs about Contexts, but the Pinax developers apparently did and I got a chance to learn this from them. This is a few sections of their code and how they use RequestContext in their apps. If you are looking at the source of some of their views you might see how they are...
