| addr | A pointer to an IP address representing the netmask. |
Definition at line 107 of file uip-fw.h.
An error message that indicates that a packet that was too large for the outbound network interface was detected.
Definition at line 155 of file uip-fw.h.
A non-error message that indicates that a zero-length packet transmission was attempted, and that no packet was sent.

Function Documentation
Register a default network interface.
All packets that don't go out on any of the other interfaces will be routed to the default interface.
- Parameters:
-
| netif | A pointer to the network interface that is to be registered. |
u8_t uip_fw_forward |
( |
void |
|
) |
|
Forward an IP packet in the uip_buf buffer.
- Returns:
- UIP_FW_FORWARDED if the packet was forwarded, UIP_FW_LOCAL if the packet should be processed locally.
void uip_fw_init |
( |
void |
|
) |
|
Initialize the uIP packet forwarding module.
u8_t uip_fw_output |
( |
void |
|
) |
|
Output an IP packet on the correct network interface.
The IP packet should be present in the uip_buf buffer and its length in the global uip_len variable.
- Return values:
-
| UIP_FW_ZEROLEN | Indicates that a zero-length packet transmission was attempted and that no packet was sent. |
| UIP_FW_NOROUTE | No suitable network interface could be found for the outbound packet, and the packet was not sent. |
- Returns:
- The return value from the actual network interface output function is passed unmodified as a return value.
void uip_fw_periodic |
( |
void |
|
) |
|
Perform periodic processing.
Register a network interface with the forwarding module.
- Parameters:
-
| netif | A pointer to the network interface that is to be registered. |
