Macro Definition Documentation

◆ ETHARP_HWADDR_LEN

#define ETHARP_HWADDR_LEN   ETH_HWADDR_LEN

Definition at line 48 of file etharp.h.

◆ IPADDR_WORDALIGNED_COPY_FROM_IP4_ADDR_T

#define IPADDR_WORDALIGNED_COPY_FROM_IP4_ADDR_T (   dest,
  src 
)    SMEMCPY(dest, src, sizeof(ip4_addr_t))

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.

Definition at line 78 of file etharp.h.
