otPlatDnssdAddressResolver struct

Starts an IPv6 address resolver. Initiates a continuous IPv6 address resolver for the specified host name in @p aResolver. Discovered addresses should be reported through the `mCallback` function in @p aResolver. The callback should be invoked whenever addresses are added or removed, providing an updated list. If all addresses are removed, the callback should be invoked with an empty list (`mAddressesLength` set to zero). The callback may be invoked immediately with cached information (if available) and potentially before this function returns. When cached result is used, the reported TTL values should reflect the original TTL from the last received response. Multiple resolvers can be started for the same host name, provided they use different callback functions. The @p aResolver and all its contained information (strings) are only valid during this call. The platform MUST save a copy of the information if it wants to retain the information after returning from this function.

Stops an IPv6 address resolver. No action is performed if no matching resolver with the same host name and callback is currently active. The @p aResolver and all its contained information (strings) are only valid during this call. The platform MUST save a copy of the information if it wants to retain the information after returning from this function.

Starts an IPv4 address resolver. Initiates a continuous IPv4 address resolver for the specified host name in @p aResolver. Discovered addresses should be reported through the `mCallback` function in @p aResolver. The IPv4 addresses are represented using the IPv4-mapped IPv6 address format in `mAddresses` array. The callback should be invoked whenever addresses are added or removed, providing an updated list. If all addresses are removed, the callback should be invoked with an empty list (`mAddressesLength` set to zero). The callback may be invoked immediately with cached information (if available) and potentially before this function returns. When cached result is used, the reported TTL values will reflect the original TTL from the last received response.

Iterates over IPv6 address resolvers. Requires `OPENTHREAD_CONFIG_MULTICAST_DNS_ENTRY_ITERATION_API_ENABLE`. On success, @p aResolver is populated with information about the next resolver. The `mCallback` field is always set to `NULL` as there may be multiple active resolvers with different callbacks. Other pointers within the `otMdnsAddressResolver` structure remain valid until the next call to any OpenThread stack's public or platform API/callback.
