otMdnsCacheInfo struct

Iterates over TXT 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 `otMdnsTxtResolver` structure remain valid until the next call to any OpenThread stack's public or platform API/callback.

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.

Iterates over IPv4 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.

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

Iterates over SRV 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 `otMdnsSrvResolver` structure remain valid until the next call to any OpenThread stack's public or platform API/callback.
