[Windows]_[C/C++]_[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;}
