关于内核模块问题（如何使用内核模块）

kewenliang

There are basically two ways of using a kernel module from a user application. The first is using a device file (usually in /dev). The kernel module registers itself with a device file when it starts up, and user applications can interact with the module by standard file operations (open, close, read, write, ioctl, etc). The other way is through the /proc interface. The module can register entries in the /proc pseudo file system, and interacts with user applications by reads and writes. We chose to use the first approach.


上面这段英语说明了什么问题，不太明白，请大侠们指教。

那么楼主对于设备文件，/proc 文件系统有概念么？
