php_getdns_context_set_resolution_type — Set the DNS query resolution type.
This function determines if DNS queries are performed with nonrecursive lookups or as a stub resolver. All implementations of this getdns library can act as recursive resolvers, and that is the default mode of the default context. Some implementations of the library are expected to also be able to act as stub resolvers.
The previously created DNS context that is to be used with this request.
The value to be set. It must be either GETDNS_RESOLUTION_RECURSING or GETDNS_RESOLUTION_STUB.
This function returns an integer response code. GETDNS_RETURN_GOOD indicates successful completion. If an implementation of the library is only able to act as a recursive resolver, a call to php_getdns_context_set_resolution_type($context, GETDNS_RESOLUTION_STUB) will return GETDNS_RETURN_CONTEXT_UPDATE_FAIL.
