Detailed explanation of Linux fork function

fork() is a very important system call in Linux and other Unix-like systems. It is used to create a new process. This new process is a copy of the current process, called a child process. The child process will obtain a copy of the parent process's code, data, heap, stack, etc., but the two processes will have different process IDs and some other resources, such as open file descriptors.

Function of fork function in Linux

Overview of the role of the fork function in Linux and code examples: In the Linux system, the fork function is a very important system call, and its main function is to create a new process. Function: Create a process: After calling the fork function, the operating system will create a new process, called a child process. The execution code of the child process is exactly the same as the parent process. The child process starts execution from the return point of the fork function. Copy the context of the parent process: The child process will copy many attributes of the parent process, including code segments, data segments, and stacks

Sharing of debugging skills for fork function failure in PHP PCNTL

Sharing debugging skills for invalid fork function in PHPPCNTL In PHP programming, the PCNTL extension provides some process control functions, such as the fork function, which can be used to create a new process. However, during use, sometimes the fork function fails, causing the child process to fail to be created normally. This article will share some debugging tips to help us solve this problem. First, let's start with a simple example. Let's say we have the following PHP code:

Analysis of the reasons why PHP PCNTL extended fork function failed

Analysis of the reasons for the failure of the PHPPCNTL extension fork function In PHP, the PCNTL extension provides a series of functions for handling process control, of which the fork function is one of the commonly used functions. Through the fork function, we can create a child process to perform a certain task, which is very useful when writing concurrent handlers. However, when using the PCNTL extended fork function, sometimes you will encounter fork failure. This article will analyze the reasons for this situation and give specific codes.
