process of the lock mechanism is similar. Declare variables, lock, execute critical code, and then unlock. The difference is that there are different restrictions on allowed re-import, some of which allow unlimited re-import, some allow only the re-import of heterogeneous operations, and some do not allow re-import operations, some can be used in sleep code, and some cannot be used in sleep code. When considering the use of different lock mechanisms, we also need to consider the CPU processing

Android, X Windows, QT, and many other applications support input devices, such as the keyboard, mouse, and touch screen, in Linux systems, or increasingly prefer the standard input subsystem. Because the input subsystem has completed the character-driven file operation interface, the core task of writing the driver is to complete the interface set aside by the input system, with little workload. But if you
Android framework, Windows MFC, and Linux represent the software framework of the application layer. The problems that the application framework solves include application message processing, UI control display and processing, resource management, and so on. The benefit of the software framework is that the framework will do 80% of the development effort for you to solve a domain problem, and you only need to complete 20% of the development effort.

It is related to the request. It is the auxiliary information returned for processing the request command. When the call is successful, 0 is returned and-1 is returned. When the value-1 is obtained, the value returned by the actual device

also resource-intensive and can degrade the performance of the system. To cope with this situation, a mutually exclusive wait option has been added to the kernel. As a result, the process of mutually exclusive waits is awakened one at a time.Mutual exclusion waits under normal circumstances, so it is no longer concerned.For the time being, the next article continues to look at some of the other advanced character driven operations Poll/select.Before the series of articles like below, welcome to
