Detailed Description

Macro Definition Documentation

◆ netif_is_up

#define netif_is_up (   netif)    (((netif)->flags & NETIF_FLAG_UP) ? (u8_t)1 : (u8_t)0)

Ask if an interface is up

Definition at line 479 of file netif.h.

Typedef Documentation

◆ netif_ext_callback_fn

Function used for extended netif status callbacks Note: When parsing reason argument, keep in mind that more reasons may be added in the future!

Parameters
netifnetif that is affected by change
reasonchange reason
argsdepends on reason, see reason description

Definition at line 668 of file netif.h.

◆ netif_nsc_reason_t

Extended netif status callback (NSC) reasons flags. May be extended in the future!

Definition at line 586 of file netif.h.

Function Documentation

◆ netif_add()

struct netif * netif_add ( struct netif netif,
void state,
netif_init_fn  init,
netif_input_fn  input 
)

Add a network interface to the list of lwIP netifs.

Parameters
netifa pre-allocated netif structure
ipaddrIP address for the new netif
netmasknetwork mask for the new netif
gwdefault gateway IP address for the new netif
stateopaque data passed to the new netif
initcallback function that initializes the interface
inputcallback function that is called to pass ingress packets up in the protocol layer stack.
It is recommended to use a function that passes the input directly to the stack (netif_input(), NO_SYS=1 mode) or via sending a message to TCPIP thread (tcpip_input(), NO_SYS=0 mode).
These functions use netif flags NETIF_FLAG_ETHARP and NETIF_FLAG_ETHERNET to decide whether to forward to ethernet_input() or ip_input(). In other words, the functions only work when the netif driver is implemented correctly!
Most members of struct netif should be be initialized by the netif init function = netif driver (init parameter of this function).
IPv6: Don't forget to call netif_create_ip6_linklocal_address() after setting the MAC address in struct netif.hwaddr (IPv6 requires a link-local address).
Returns
netif, or NULL if failed.
