call exit

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

1. Exit FunctionThe C,c++ function exit is used to terminate the current program, and the function is defined as follows: void exit (int status); The official notes are as follows:Terminates the process normally, performing the regular

1. What is a process? From the user's perspective, a process is a program execution process.From the core of the operating system, processes are the basic units of resources such as memory allocated by the operating system and CPU time slice.A

// XK> foreshadowing 1: fork () and Exec The only way to derive a new process in UNIX is the fork () function (some systems may provide its various variants ). All descriptors opened in the parent process are shared by the child process after

Method of Process Termination: 1. Normal termination: Return from main; Call exit; Call _ exit; 2. exceptional termination: Call abort; Terminated by a signal. Difference between exit and _ Exit: # Include Void exit (INT status ); # Include Void _

So far, thread synchronization is most commonly used to ensure that multiple threads are mutually exclusive to shared resources. For synchronizing multiple threads in a single process for mutex access, the critical_section structure of Win32 API and

Before learning a process, you must first understand the execution environment of the process. Main Function The process is always executed from the main function. During programming, the program runs from the main function. Its prototype is as

1. Process Termination There are eight ways to terminate the process (1) return from main (2) Call exit; (3) Call _ exit or _ exit; (4) The last thread returns from its startup history (5) The last thread calls pthread_exit; There are three methods

In general, in order to end our program, we will use return or call exit () in the main function (). There are also exitprocess () and terminateprocess () functions in windows.The purpose of this article is to compare the differences between the

There are often multiple exit procedures in the program, and some cleaning work should be performed when the program exits. If there is a method that can provide no relation to the program exit method to process the program exit, it is necessary to

  Process Termination: There are eight methods to terminate the process, of which five are normal termination. (1) return from main (2) Call exit (3) Call _ exit or _ exit (4) The last current response from the startup routine (5) The

View Linux Processes Linux Process Processes are the basic unit of Transaction Management in Linux. All processes have their own independent processing environment and system resources, and they cannot directly access the resources of the other
