Field Documentation

chksum_len_rx

u16_t udp_pcb::chksum_len_rx

used for UDP_LITE only

local_ip

ip_addr_t udp_pcb::local_ip

Common members of all PCB types

local_port

u16_t udp_pcb::local_port

ports are in host byte order

mcast_ifindex

u8_t udp_pcb::mcast_ifindex

outgoing network interface for multicast packets, by interface index (if nonzero)

mcast_ip4

ip4_addr_t udp_pcb::mcast_ip4

outgoing network interface for multicast packets, by IPv4 address (if not 'any')

mcast_ttl

u8_t udp_pcb::mcast_ttl

TTL for outgoing multicast packets

recv

udp_recv_fn udp_pcb::recv

receive callback function

recv_arg

void* udp_pcb::recv_arg

user-supplied argument for the recv callback
