I am trying to open UART1 but it is returning positive 9 num

Legacy Open AT

Dear All,
I am trying to open UART1 by using OS API but it is returning positive 9 digit number. I am not aware about this.
interface_handler = adl_OpenDevice(DF_UART_CLID, &uart_settings);
I gone through the Open at documents found that positive value is SUCCESS, Negative value is FAILED.

Is it address?
Please share your knowledge. Thanks

As you can refer in the ‘ADL user guide’, this is the UART service provider handle on success, to be used in further Open
UART service function calls.
