Link-Detection service API

Detailed Description

Link-Detection service is used for automatic detection of a network-link connection status change from connected to disconnected state and vice versa.
After the Link-Detection service is initialized by calling the fnet_link_init() function, the user application should call the main service-polling function fnet_poll_service() periodically in background.

For the Link-Detection service example, refer to the FNET Shell demo source code.
Configuration parameters:

Data Structures

struct  fnet_link_params
 Initialization parameters for the fnet_llmnr_init() function. More...
 

Typedefs

typedef fnet_int32_t fnet_link_desc_t
 Link-Detection service descriptor. More...
 
typedef void(* fnet_link_callback_t) (fnet_netif_desc_t netif, fnet_bool_t connected, void *callback_param)
 Link-Detection event handler callback function prototype, which is called when a networking interface has changed its link status from connected stae to disconnected or vice versa. More...
 

Functions

fnet_link_desc_t fnet_link_init (struct fnet_link_params *params)
