ip.h
IP API.
Defines
-
LWIP_IP_HDRINCL
-
LWIP_IP_CHECK_PBUF_REF_COUNT_FOR_TX(p)
pbufs passed to IP must have a ref-count of 1 as their payload pointer gets altered as the packet is passed down the stack
-
IP_PCB_NETIFHINT
-
IP_PCB
This is the common part of all PCB types.
It needs to be at the beginning of a PCB type definition. It is located here so that changes to this common part are made in one location instead of having to change all PCB structs.
-
pcb_tci_init(pcb)
-
SOF_REUSEADDR
-
SOF_KEEPALIVE
-
SOF_BROADCAST
-
SOF_INHERITED
-
ip_current_netif()
Get the interface that accepted the current packet.
This may or may not be the receiving netif, depending on your netif/network setup. This function must only be called from a receive callback (udp_recv, raw_recv, tcp_accept). It will return NULL otherwise.
-
ip_current_input_netif()
Get the interface that received the current packet.
This function must only be called from a receive callback (udp_recv, raw_recv, tcp_accept). It will return NULL otherwise.
-
ip_current_header_tot_len()
Total header length of ip(6)_current_header() (i.e.
after this, the UDP/TCP header starts)
-
ip_current_src_addr()
Source IP address of current_header.
Union source address of current_header.
-
ip_current_dest_addr()
Destination IP address of current_header.
Union destination address of current_header.
-
ip_current_src_addr()
Source IP address of current_header.
Union source address of current_header.
-
ip_current_dest_addr()
Destination IP address of current_header.
Union destination address of current_header.
-
ip_get_option(pcb, opt)
Gets an IP pcb option (SOF_* flags)
-
ip_set_option(pcb, opt)
Sets an IP pcb option (SOF_* flags)
-
ip_reset_option(pcb, opt)
Resets an IP pcb option (SOF_* flags)
-
ip_route_get_local_ip(src, dest, netif, ipaddr)

Public Members
-
struct netif *current_netif
The interface that accepted the packet for the current callback invocation.
-
struct netif *current_input_netif
The interface that received the packet for the current callback invocation.
-

Total header length of current_ip4/6_header (i.e.
after this, the UDP/TCP header starts)
-
struct netif *current_netif
