Function Documentation

void uip_fw_default ( struct uip_fw_netif * netif )

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.

Definition at line 515 of file uip-fw.c.

uint8_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.

Definition at line 403 of file uip-fw.c.

void uip_fw_init ( void )

Initialize the uIP packet forwarding module.

Definition at line 185 of file uip-fw.c.

uint8_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.

Definition at line 354 of file uip-fw.c.

void uip_fw_periodic ( void )

Perform periodic processing.

Definition at line 525 of file uip-fw.c.

void uip_fw_register ( struct uip_fw_netif * netif )

Register a network interface with the forwarding module.

Parameters:

netif A pointer to the network interface that is to be registered.
