Every Wireless Manager layer net_wifi_mgr.c

Prototype

          static void NetWiFiMgr_IO_Ctrl (NET_IF     *p_if,
                                          CPU_INT08U  opt,
                                          void       *p_data,
                                          NET_ERR    *p_err);

Note that since every Wireless Manager’s IO_Ctrl() function is accessed only by function pointer via the Wireless Manager’s API structure, it doesn’t need to be globally available and should therefore be declared as ‘static’.

μC/TCP-IP defines the following default options:

• NET_DEV_LINK_STATE_GET_INFO
• NET_DEV_LINK_STATE_UPDATE

The NET_DEV_LINK_STATE_GET_INFO option expects p_data to point to a variable of type NET_DEV_LINK_WIFI for the case of an Ethernet driver. This variable has one field, link state, which are filled in by the device driver API. μC/TCP-IP internally uses this option code in order to periodically poll the driver for linkstatelink state.
