/*! \file dns/rdatasetiter.h
 * \brief
 * The DNS Rdataset Iterator interface allows iteration of all of the
 * rdatasets at a node.
 *
 * The dns_rdatasetiter_t type is like a "virtual class".  To actually use
 * it, an implementation of the class is required.  This implementation is
 * supplied by the database.
 *
 * It is the client's responsibility to call dns_rdataset_disassociate()
 * on all rdatasets returned.
 *
 * XXX more XXX
 *
 * MP:
 *\li	The iterator itself is not locked.  The caller must ensure
 *	synchronization.
 *
 *\li	The iterator methods ensure appropriate database locking.
 *
 * Reliability:
 *\li	No anticipated impact.
 *
 * Resources:
 *\li	TBS
 *
 * Security:
 *\li	No anticipated impact.
 *
 * Standards:
 *\li	None.
