Is there a function to monitor the status of data being sent via USB- Virtual Com Port in STM32F429?

I am using standard USB libraries available on ST website. Is there a function available in these libraries where I can check a status flag and confirm whether a data transfer via USB virtual Com port is complete or not?

CubeMX libraries? You can check the state variable

  USBD_CDC_HandleTypeDef *hcdc = (USBD_CDC_HandleTypeDef*)hUsbDeviceHS.pClassData;
  if (hcdc->TxState != 0){
    return USBD_BUSY;
  }

.
