Detailed Description

AutoIP Automatic LinkLocal IP Configuration.

Definition in file libraries/net/lwip/lwip/include/ipv4/lwip/autoip.h.

Function Documentation

void autoip_arp_reply ( struct netif *  netif,
struct etharp_hdr *  hdr 
)

Handles every incoming ARP Packet, called by etharp_arp_input.

Parameters:
netifnetwork interface to use for autoip processing
hdrIncoming ARP packet

Definition at line 486 of file lwip_autoip.c.

void autoip_init ( void   )

Init srand, has to be called before entering mainloop.

Definition at line 129 of file lwip_autoip.c.

void autoip_network_changed ( struct netif *  netif )

Handle a possible change in the network configuration.

If there is an AutoIP address configured, take the interface down and begin probing with the same address.

Definition at line 375 of file lwip_autoip.c.

void autoip_set_struct ( struct netif *  netif,
struct autoip *  autoip 
)

Set a struct autoip allocated by the application to work with.

Set a struct autoip allocated by the application to work with.

Using this prevents autoip_start to allocate it using mem_malloc.

Parameters:
netifthe netif for which to set the struct autoip
dhcp(uninitialised) dhcp struct allocated by the application

Definition at line 141 of file lwip_autoip.c.

err_t autoip_start ( struct netif *  netif )

Start AutoIP client.

Parameters:
netifnetwork interface on which start the AutoIP client

Definition at line 293 of file lwip_autoip.c.

err_t autoip_stop ( struct netif *  netif )

Stop AutoIP client.

Parameters:
netifnetwork interface on which stop the AutoIP client

Definition at line 389 of file lwip_autoip.c.

void autoip_tmr ( void   )

Has to be called in loop every AUTOIP_TMR_INTERVAL milliseconds.

Definition at line 400 of file lwip_autoip.c.
