## Detailed Description

lwIP network interface abstraction

## Function Documentation

## netif_get_ip6_addr_match()

s8_t netif_get_ip6_addr_match | ( | struct netif * | netif,
|  | const ip6_addr_t * | ip6addr )

Checks if a specific local address is present on the netif and returns its index. Depending on its state, it may or may not be assigned to the interface (as per RFC terminology).

The given address may or may not be zoned (i.e., have a zone index other than IP6_NO_ZONE). If the address is zoned, it must have the correct zone for the given netif, or no match will be found.

Parameters

  netif | the netif to check
  ip6addr | the IPv6 address to find

Returns
  >= 0: address found, this is its index -1: address not found on this netif

## netif_poll()

void netif_poll | ( | struct netif * | netif | ) |

Call netif_poll() in the main loop of your application. This is to prevent reentering non-reentrant functions like tcp_input(). Packets passed to netif_loop_output() are put on a list that is passed to netif->input() by netif_poll().

## Variable Documentation

## netif_default

struct netif* netif_default

The default network interface.

## netif_list

struct netif* netif_list

The list of network interfaces.
