Today we will use the famous pipe mkfifo to realize a simple version of QQ dialogue function.
Step 1: first create two processes Talka C and talkb c；
Step 2: talk a C and talkb C is responsible for checking whether two pipelines have been created. If not, it is necessary to create pipelines;
Step 3: talk a C open pipe 1 in a write only mann ...

In the development of industrial instruments, the physical quantities measured by the instruments are often converted into current signals for output and transmission. The characteristics of strong anti-interference and long transmission distance of current signals are widely used in industrial instruments.
ADI's AD5420 chip directly converts ...

Everyone who needs to learn LLVM must know that this is a powerful open source compilation tool chain. In fact, the more you study later, you will find that this thing and the design idea are very awesome. This thing can bring pluggable optimization to the compilation process, which is very convenient. This article does not talk about what LLVM ...

In C program:
When dealing with data (files) outside the program code, we use the concept of stream to realize the data exchange between the process's virtual memory and files.
——FILE stream: the C standard library provides FILE (named FILE because linux treats all mechanisms as files). The FILE object is a structure that contain ...

When we issue some commands to Linux, Shell translates these commands into the actions that kernel can understand, then calls the kernel, operates the hardware, completes the operation, and then translates the signals into adult understandable forms.
Shell is also a p ...
