/*! \file dns/clientinfo.h
 * \brief
 * The DNS clientinfo interface allows libdns to retrieve information
 * about the client from the caller.
 *
 * The clientinfo interface is used by the DNS DB and DLZ interfaces;
 * it allows databases to modify their answers on the basis of information
 * about the client, such as source IP address.
 *
 * dns_clientinfo_t contains a pointer to an opaque structure containing
 * client information in some form.  dns_clientinfomethods_t contains a
 * list of methods which operate on that opaque structure to return
 * potentially useful data.  Both structures also contain versioning
 * information.
