distinguish between different kinds of devices, while the secondary device number is used to differentiate multiple devices of the same type.The Linux kernel uses a virtual file system (SYSTEM,VFS) as an interface for interacting with each file system. This provides a standard interface for any type of file system communication within Linux. When each file system is mounted and used, the VFS will slow down

The EXPORT_SYMBOL_GPL () exported symbol is encapsulated once again in the form of Export_symbol (), while the other modules do not call the kernel directly but call the wrapper function. 4.1 of what you see. Such a practice is also controversial.Figure 4.1 EXPORT_SYMBOL_GPL again with Export_symbol exportGenerally feel. The conservative approach is that the

The difference is that encodeURI () does not encode special characters that are themselves URIs, such as colons, forward slashes, question marks, and well sizes, while encodeuricomponent () encodes any non-standard characters it discovers.

Hello3There are enough reviews. It's time to build a complete windows application-hello3. Although the entire program file of hello3 and all the examples in the book can be found in the attached book CD, I still suggest that for the initial examples, instead of simply loading project files from CD, you should manually enter the entire example. Through this slightly boring work, you will experience the differences in the development process and program nuances between the standard Win32 program a
