prot_etharp.h

ARP protocol definitions.

Defines

IPADDR_WORDALIGNED_COPY_TO_IP4_ADDR_T(dest, src): MEMCPY-like copying of IP addresses where addresses are known to be 16-bit-aligned if the port is correctly configured (so a port could define this to copying 2 u16_t’s) - no NULL-pointer-checking needed.

IPADDR_WORDALIGNED_COPY_FROM_IP4_ADDR_T(dest, src): MEMCPY-like copying of IP addresses where addresses are known to be 16-bit-aligned if the port is correctly configured (so a port could define this to copying 2 u16_t’s) - no NULL-pointer-checking needed.

Variables

struct ip4_addr_wordaligned

#include <prot_etharp.h>

struct ip4_addr_wordaligned is used in the definition of the ARP packet format in order to support compilers that don’t have structure packing.
