如何获取每个进程的command line

Question

LONG status = NtQueryInformationProcess(hProcess,
                                                0,
                                                pinfo,
                                                sizeof(PVOID)*6,
                                                NULL);
        PPEB ppeb = (PPEB)((PVOID*)pinfo)[1];
        PPEB ppebCopy = (PPEB)malloc(sizeof(PEB));
        BOOL result = ReadProcessMemory(hProcess,
                                        ppeb,
                                        ppebCopy,
                                        sizeof(PEB),
                                        NULL);        PRTL_USER_PROCESS_PARAMETERS pRtlProcParam = ppebCopy->ProcessParameters;
        PRTL_USER_PROCESS_PARAMETERS pRtlProcParamCopy =
            (PRTL_USER_PROCESS_PARAMETERS)malloc(sizeof(RTL_USER_PROCESS_PARAMETERS));
        result = ReadProcessMemory(hProcess,
                                   pRtlProcParam,
                                   pRtlProcParamCopy,
                                   sizeof(RTL_USER_PROCESS_PARAMETERS),
                                   NULL);
        PWSTR wBuffer = pRtlProcParamCopy->CommandLine.Buffer;
        USHORT len =  pRtlProcParamCopy->CommandLine.Length;
        PWSTR wBufferCopy = (PWSTR)malloc(len);
        result = ReadProcessMemory(hProcess,
                                   wBuffer,
                                   wBufferCopy, // command line goes here
                                   len,
                                   NULL);

Answer 1

NtQueryInformationProcess需要用到那个头文件，我直接拷过去编译不过，能否给一段比较完整的代码？
