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

[Er.Anil]

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;
 }

.

I am using "STM32F USB Drivers & Liberary"

I see no useful Google results for "STM32F USB Drivers & Liberary".
