http://blog.csdn.net/jason314/article/details/5640969The fork () call will copy a new process that is almost identical to the current process (except for the fork's return value), each of which has its own space, each with its own local variables,

The Linux kernel is a great circus performer who plays juggling carefully between process and system resources and keeps the system running properly. At the same time, the kernel is fair: it allocates resources equitably to processes. But what if

The tree-like process structure in Linux provides great convenience for management processes. Both kernel-based process management and user-based process management have benefited a lot, and it is also useful for auditing, no matter what process is

I. Introduction to fork   A process, including code, data, and resources allocated to the process. The fork () function creates a process that is almost identical to the original process through system calls, that is, the two processes can do

Before creating a process, let's briefly review the sys_clone () system call in the previous blog:Asmlinkage int sys_clone (struct pt_regs regs){Unsigned long clone_flags;Unsigned long newsp;Int _ User * parent_tidptr, * child_tidptr; Clone_flags =

In Unix programming, learning to use fork and signal is quite basic. Fork () and signal are often used in daemon resident programs, such as a4c. tty, yact, and chdrv are also useful for most large programs, such as Mozilla, Apache, and

Abstract: This section describes some basic operations on a process. Through this section, we will learn how to generate a sub-process, how the process changes its execution image, and synchronization of parent and child processes. We also learned

#include /*provides a definition of type pid_t*/#includepid_t Wait (int*status) Once the process has called wait, it blocks itself immediately, and the wait automatically parses if a child process of the current process has exited, and if it finds

Message Queue Message Queue (also called Message Queue) can overcome some shortcomings of the early UNIX communication mechanism. As one of the early UNIX communication mechanisms, the amount of information that a signal can transmit is limited.

Causes and solutions for zombie Processes Generation of zombie processes: When a process creates a sub-process, its operation is asynchronous. That is, the parent process cannot predict when the child process will end. If the child process is too
