| #define | IPADDR_WORDALIGNED_COPY_TO_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. More... | |
