What does this line of code do? (void)<variable>;

Below is an example:

case CYBLE_EVT_GAP_AUTH_COMPLETE:            

            authInfo = (CYBLE_GAP_AUTH_INFO_T *)eventParam;

            (void)authInfo;

            DBG_PRINTF("AUTH_COMPLETE: security:%x, bonding:%x, ekeySize:%x, authErr %x \r\n",

                                    authInfo->security, authInfo->bonding, authInfo->ekeySize, authInfo->authErr);

            break;

Hello,

(void)authInfo; This is added to avoid any compiler warnings in case if the authInfo is unused in your code.

This not any specific requirement for the BLE design.

Thanks,
