从进程ID(Win32)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 可以获取PID列表，但是如何从pid获取进程名称?我不想在该进程上调用OpenProcess，因为它并不总是起作用(就像其他进程是由其他用户运行一样).

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

您可以使用

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\n", pe32.th32ProcessID, pe32.szExeFile);
            } while(Process32Next(hSnapshot, &pe32));
         }
         CloseHandle(hSnapshot);
    }
}
