| | [read] |
Add a network interface to the list of lwIP netifs.
- Parameters:
-
| netif | a pre-allocated netif structure |
| ipaddr | IP address for the new netif |
| netmask | network mask for the new netif |
| gw | default gateway IP address for the new netif |
| state | opaque data passed to the new netif |
| init | callback function that initializes the interface |
| input | callback function that is called to pass ingress packets up in the protocol layer stack. |
- Returns:
- netif, or NULL if failed.

struct netif* netif_find |
( |
char * |
name |
) |
[read] |
Find a network interface by searching for its name
- Parameters:
-
| name | the name of the netif (like netif->name) plus concatenated number in ascii representation (e.g. 'en0') |
Definition at line 290 of file netif.c.
void netif_remove |
( |
struct netif * |
netif |
) |
|
Remove a network interface from the list of lwIP netifs.
- Parameters:
-
| netif | the network interface to remove |

| | |
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 |
Definition at line 221 of file netif.c.
void netif_set_default |
( |
struct netif * |
netif |
) |
|
Set a network interface as the default network interface (used to output all packets for which no specific route is found)
- Parameters:
-
| netif | the default network interface |
Definition at line 430 of file netif.c.
void netif_set_down |
( |
struct netif * |
netif |
) |
|
Bring an interface down, disabling any traffic processing.
- Note:
- : Enabling DHCP on a down interface will make it come up once configured.
- See also:
- dhcp_start()

void netif_set_gw |
( |
struct netif * |
netif, |
|
|

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
Definition at line 388 of file netif.c.
void netif_set_ipaddr |
( |
struct netif * |
netif, |
|
|
ip_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
Definition at line 323 of file netif.c.

void netif_set_netmask |
( |
struct netif * |
netif, |
|
|
ip_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
Definition at line 409 of file netif.c.
void netif_set_up |
( |
struct netif * |
netif |
) |
|
Bring an interface up, available for processing traffic.
- Note:
- : Enabling DHCP on a down interface will make it come up once configured.
