Как в CreateProcess задать параметры запуска процесса ?

const char* steam ="G:\\steam\\Steam.exe";
STARTUPINFO si;
    PROCESS_INFORMATION pi;
 
    ZeroMemory(&si, sizeof(si));
    si.cb = sizeof(si);
    ZeroMemory(&pi, sizeof(pi));
    if (!
        CreateProcess
        (
            TEXT(steam),
            NULL, NULL, NULL, FALSE,
            CREATE_NEW_CONSOLE,
            NULL, NULL,
            &si,
            &pi
        )
        )
    {
        cout << "Unable to execute.";
        
    }
 
        cout << "A value that can be used to identify a process." << pi.dwProcessId << endl;
        cout << "A value that can be used to identify a thread. " << pi.dwThreadId << endl;

char cmd[] =  "-login логин пароль";
CreateProcessA(steam, cmd, ...................

char cmd[] =  "G:\\steam\\Steam.exe -login логин пароль";
CreateProcessA(NULL, cmd, ...................

const char* steam ="G:\\steam\\Steam.exe";
    char cmd[] = "-login dsds dsds";
 
ZeroMemory(&si, sizeof(si));
    si.cb = sizeof(si);
    ZeroMemory(&pi, sizeof(pi));
    if (!
        CreateProcess
        (
            TEXT(steam,cmd),
            NULL,NULL, NULL, FALSE,
            CREATE_NEW_CONSOLE,
            NULL, NULL,
            &si,
            &pi
        )
        )

TCHAR cmd[] =  _T("G:\\steam\\Steam.exe -login логин пароль");
CreateProcess(NULL, cmd, ...................
