void fnet_dhcp_cln_set_callback_discover ( fnet_dhcp_cln_desc_t  desc, fnet_dhcp_cln_callback_t  callback_discover, void *  cookie  ) Registers the "Discover message sent" DHCP event handler callback. Parameters desc DHCP client descriptor. callback_discover Pointer to the callback function defined by fnet_dhcp_cln_callback_t. cookie Optional application-specific parameter. It's passed to the callback_discover callback function as input parameter. See also FNET_CFG_DHCP_CLN_RESPONSE_TIMEOUT This function registers the callback_discover callback function for the "Discover message sent" event. This event occurs when the DHCP client sends the DHCP discover message. A user interface program may use it for indication of retransmission attempts. To stop the event handling, set the callback_discover parameter to zero value.
