CCS/CC2650: Usage of GAPRole_GetParameter function

Tool/software: Code Composer Studio

Hi,

I want to get advertising status of BLE device. I have used following code to get status

    char status, value;
    status = GAPRole_GetParameter(GAPROLE_ADVERT_ENABLED, &value);

This would get value of Parameter GAPROLE_ADVERT_ENABLED variable, correct?

Is this correct way of usage?

Thanks
