int ot_dns_offload_register

(

)

Register Zephyr DNS offload using OpenThread DNS client.

Installs a Zephyr socket_dns_offload implementation via socket_offload_dns_register whose getaddrinfo handler resolves node using otDnsClientResolveIp4Address first (IPv4 A records as NAT64-mapped IPv6 when supported), then otDnsClientResolveAddress (AAAA). Successful lookups return NET_AF_INET6 sockaddr entries only.

Return values

0	Registration succeeded.
-EALREADY	A handler was already registered.
