WIN32 根据程序名(映像名称)终止外部程序

场景:

1.有时候需要调用外部程序，但是外部程序有可能崩溃挂起，这样这个进程就没法结束，所以再在下次调用前需要先结束之前调用的。

2.没考虑到权限问题，应该是只能终止当前用户启动的进程.

 

 

#include <stdio.h>
#include <string.h>

#include <windows.h>
#include <Tlhelp32.h>

#include <vector>

void TerminateProcessByName(PCWSTR name)
{
    DWORD pid = 0;

    // Create toolhelp snapshot.
    HANDLE snapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
    PROCESSENTRY32W process;
    ZeroMemory(&process, sizeof(process));
    process.dwSize = sizeof(process);

    std::vector<DWORD> pids;
    // Walkthrough all processes.
    if (Process32FirstW(snapshot, &process))
    {
        do
        {
            // Compare process.szExeFile based on format of name, i.e., trim file path
            // trim .exe if necessary, etc.
            if (!wcscmp(process.szExeFile, name))
            {
               pid = process.th32ProcessID;
               pids.push_back(pid);
            }
        } while (Process32NextW(snapshot, &process));
    }

    CloseHandle(snapshot);

    size_t size = pids.size();
    for(size_t i = 0; i < size; ++i)
    {
        HANDLE one_process = OpenProcess(PROCESS_TERMINATE, FALSE, pids[i]);
        BOOL res = TerminateProcess(one_process,0);
        if(res)
        {
            WaitForSingleObject(one_process,1000);
        }
    }
}

int main(int argc, char *argv[])
{
    printf("Hello, world\n");

    std::vector<DWORD> pids;
    TerminateProcessByName(L"notepad.exe");

    return 0;
}
