Data Structure Documentation

◆ pbuf

struct pbuf

Main packet buffer struct

Definition at line 199 of file tcpip.h.

Collaboration diagram for pbuf:

Data Fields
struct pbuf *	next	next pbuf in singly linked pbuf chain
void *	payload	pointer to the actual data in the buffer
u16	tot_len	total length of this buffer and all next buffers in chain belonging to the same packet. For non-queue packet chains this is the invariant: p->tot_len == p->len + (p->next? p->next->tot_len: 0)
u16	len	length of this buffer
u8	type	pbuf_type as u8 instead of enum to save space
u8	flags	misc flags
u16	ref	the reference count always equals the number of pointers that refer to this pbuf. This can be pointers from an application, the stack itself, or pbuf->next pointers from a chain.

◆ ip4_addr

struct ip4_addr

This is the aligned version of ip4_addr_t, used as local variable, on the stack, etc.

Definition at line 236 of file tcpip.h.

◆ ip6_addr

struct ip6_addr

This is the aligned version of ip6_addr_t, used as local variable, on the stack, etc.

Definition at line 390 of file tcpip.h.

◆ netif

struct netif

Generic data structure used for all lwIP network interfaces. The following fields should be filled in by the initialization function for the device driver: hwaddr_len, hwaddr[], mtu, flags

Data Fields
struct netif *	next	pointer to next in linked list
ip_addr_t	ip_addr	IP address configuration in network byte order
ip_addr_t	netmask
ip_addr_t	gw
netif_input_fn	input	This function is called by the network device driver to pass a packet up the TCP/IP stack.
netif_output_fn	output	This function is called by the IP module when it wants to send a packet on the interface. This function typically first resolves the hardware address, then sends the packet. For ethernet physical layer, this is usually etharp_output()
netif_linkoutput_fn	linkoutput	This function is called by ethernet_output() when it wants to send a packet on the interface. This function outputs the pbuf as-is on the link medium.
