The only way to create a new process in Linux is to use the fork () function. The fork () function is a very important function in Linux, and there are some differences from previous functions, because the fork () function looks like it executes

Create a new process with the fork function in Unix/linux. The process is created by the currently existing process calling the fork function, and the forked process is called a subprocess, and the creator is called the parent process. The function

Let's take a look at an example of using fork to invoke the EXECLP () function to implement the PS or LS command under Linux: #include "sys/types.h" #include "unistd.h" #include "stdio.h" #include "stdlib.h" int main () { pid_t result;

The Linux system provides a fork function to create child processes. The fork function, compared to the normal function, is a special place where the fork function is called once, but returns two times. Once returned in the parent process, another

For users who write multi-process programs in Linux, fork is one of the most difficult concepts to understand: it executes but returns two values at a time. First, let's look at the prototype of the fork function: # I nclude # I nclude Pid_t fork (

In Linux, the system call that generates a new process is the fork function. This function name means "Forks" in English. Why is this name used? Because a process is running, if fork is used, another process is generated, so the process is "Forked",
