formally proven to be correct through complex and precise techniques can also be flawed. Why? One reason is that validation must make many assumptions, and often these assumptions are not entirely correct. In any case, most programs are not rigorously tested for a variety of reasons. Moreover, even if there is no defect today (unlikely), changes in maintenance or changes in the environment may introduce defects. So, to deal with the actual problem, we have to somehow develop secure programs, ev

variables, and the parent process has also seen this modification. The vfork function may occur because the fork of the early system did not implement the write-time replication technology, resulting in a lot of useless work in each fork call (in most cases, it is called exec to execute a new program after fork) the efficiency is not high, so the vfork function is created. The current implementation basically uses the write-time replication technolog

After reading the first chapter of the Bible, I am familiar with the entire programming process of Unix. The use of C language is now available. From the Unix architecture, the original operating system, including the kernel and some other software, is often called the Linux kernel as the operating

The recommended star rating for this book is: 5 stars. After all, it is a classic book, Nothing to say.As far as the Assembly itself is concerned, the preparation of high-efficiency programs and the optimization, commissioning, and reverse engineering of the project is a foundation; in terms of the theoretical operating system, the assembly lets you understand th

machines, it will take a second on programmers. 14. Generation Principle: Avoid manual hack and write programs to generate programs as much as possible. 15. Optimization Principle: you must first have the original type before carving, and learn to go before running. 16. Principles of diversity: never believe in the so-called "no two methods" assertions. 17. Expansion principle: design focuses on the future, and the future is always faster than expected. In addition: A program only does one thi

IPC (inter-process communication, interprocess communication) can have three ways of sharing information (along with the file system, with the kernel, with shared memory). (Of course, although it is interprocess communication, it can also be connected with threads).The relative IPC continuity (persistence of IPC Object) also has three kinds: with process (process-persistent IPC) IPC object persists until the last owning process

Judging from these years of experience, these language tutorials are well written, but in addition, there are few bright spots. In other words, these books are very rigorous, very sophisticated, if the reader has sufficient strength, through their mastery of a language programming technology

System Call Failure Reason analysis In UNIX programming, we often use system calls to accomplish the desired function, while at the same time we need to pay large sections of code to detect, output errors, and other contingencies. The following are the possible causes of a system
