Win32 Functions - Open Process

This page demonstrates the opening of Windows processes using the Win32 API. Understanding these functions is crucial for interacting with the operating system.

Introduction

The Win32 API provides a vast set of functions to interact with the Windows operating system. Open Process is a fundamental function used to initiate the execution of a specific process.

Function Overview

The `OpenProcess` function is a powerful tool that allows you to manage the Windows process environment. It's used to obtain a handle to a running process, opening it for execution.

Code Example

Here's a basic example:


            #include 

            int OpenProcess(
                ID_ процес,      // The process ID to open
                LPHANDLE  подробный_handle,  // The process ID to open
                1,              // The parent process
                0,              // The thread
                0,              // The security options
                0,              // The access rights
                0,              // The number of the current thread
                0                // The number of the current thread
            );

            if (OpenProcess != NULL) {
                // Get the handle to the process
                LPHANDLE  подробный_handle = OpenProcess(
                    0,      // The parent process
                    0,      // The thread
                    0,      // The security options
                    1,      // The process ID
                    0,      // The thread
                    0,      // The security options
                    0,      // The number of the current thread
                    0
                );

                if (подробный_handle != NULL) {
                    printf("Process opened successfully.\n");
                } else {
                    printf("Failed to open process.\n");
                }
            } else {
                printf("Failed to open process.\n");
            }

Usage

You can use OpenProcess to: Retrieve a process handle; Start a process; Close a process; ...
