**Example**

.. code-block:: cpp

    // Simulate: DRL program triggers a popup (e.g., "Continue operation?")
    printf("[DRL Popup] Continue operation? (1 = Resume, 0 = Cancel): ");
    int userInput;
    std::cin >> userInput;

    // Send response to DRL popup based on user input
    if (userInput == 1) {
        Drfl.tp_popup_response(POPUP_RESPONSE_RESUME);
        printf("User selected RESUME — continuing program execution.\n");
    } else {
        Drfl.tp_popup_response(POPUP_RESPONSE_STOP);
        printf("User selected STOP — halting DRL execution.\n");
    }

This example simulates handling a **DRL popup event** that requires user confirmation.  
The program prompts for input and sends a corresponding response  
(`RESUME` or `STOP`) using `tp_popup_response()`, allowing the DRL program  
to either **continue or terminate** based on the user’s decision.
