This question is from the Forum. The original question is how to achieve win + L. The first reaction is to simulate the buttons. In fact, developers should not use this idea when they come up. If they cannot, they should consider pressing the buttons. The solution code is as follows:Using System; Namespace Leleapplication2 ... { Class Program ... { Static Void Main ( String [] ARGs) ... { System

services provided by the operating system kernel.Logically, a system call can be viewed as an interface between the kernel and the user-space program-the system call passes the application's request to the kernel, invokes the corresponding kernel function to complete the re

1. What is system call In the Linux World, we often encounter the term system call. The so-called system call is a series of functions provided by the kernel with very powerful functions. These

process must pass a parameter named system call number to identify the required system calls. An integer is returned for all system calls. These return values are different from the conventions for encapsulating the return values of routines. In the kernel, an integer or 0 indicates the successful completion of the

　　In the previous article introduced several multi-channel programming memory management mode, the Exchange memory management is most flexible and advanced. But there are a lot of major problems with this strategy, and the two most important issues are space waste and program size constraints. So what's the solution to the problem of swapping memory? The answer is paging, which is the "only way" that we sol

statuses when the collection process exits. It is a pointer to the int type. But if we don't care about how this sub-process died, we just want to destroy it (in fact, in most cases, we will think like this ), we can set this parameter to null, as shown below: pid = wait(NULL); If the call succeeds, wait returns the ID of the collected sub-process. If the call process does not have a sub-pr
