Function Documentation

netif_set_addr()

void netif_set_addr	(	struct netif *	netif,
		const ip4_addr_t *	ipaddr,
		const ip4_addr_t *	netmask,
		const ip4_addr_t *	gw
	)

Change IP address configuration for a network interface (including netmask and default gateway).

Parameters

netif	the network interface to change
ipaddr	the new IP address
netmask	the new netmask
gw	the new default gateway

netif_set_gw()

void netif_set_gw	(	struct netif *	netif,
		const ip4_addr_t *	gw
	)

Change the default gateway for a network interface

Parameters

netif	the network interface to change
gw	the new default gateway

Note

call netif_set_addr() if you also want to change ip address and netmask

netif_set_ipaddr()

void netif_set_ipaddr	(	struct netif *	netif,
		const ip4_addr_t *	ipaddr
	)

Change the IP address of a network interface

Parameters

netif	the network interface to change
ipaddr	the new IP address

Note

call netif_set_addr() if you also want to change netmask and default gateway

netif_set_netmask()

void netif_set_netmask	(	struct netif *	netif,
		const ip4_addr_t *	netmask
	)

Change the netmask of a network interface

Parameters

netif	the network interface to change
netmask	the new netmask

Note

call netif_set_addr() if you also want to change ip address and default gateway
