从进程 id (win32) 中获取进程名称 [英] get process name from process id (win32)

问题描述

我需要获取 Windows 系统上所有进程的列表，包括名称和 PID.
EnumProcess 可以获得pid列表，但如何从 pid 中获取进程名称?我不想在进程上调用 OpenProcess，因为这并不总是有效(就像另一个进程由不同的用户运行一样).

I need to get a list of all processes on a windows system including names and PID.
EnumProcess can obtain a list of pids, but how do I get the process name from the pid? I don't want to call OpenProcess on the process as that doesn't always work (like if the other process is run by a different user).

推荐答案

Ýou 可以使用 工具帮助 API.
以下代码将显示每个进程的 pid 和 name.

Ýou can get the process identifier and name for all running processes using the ToolHelp API.
The following code will display the pid and name for each process.

void showProcessInformation() {
    HANDLE hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
    if(hSnapshot) {
        PROCESSENTRY32 pe32;
        pe32.dwSize = sizeof(PROCESSENTRY32);
        if(Process32First(hSnapshot, &pe32)) {
            do {
               printf("pid %d %s
", pe32.th32ProcessID, pe32.szExeFile);
            } while(Process32Next(hSnapshot, &pe32));
         }
         CloseHandle(hSnapshot);
    }
}
