dns_sdb_register(const char *drivername, const dns_sdbmethods_t *methods,
		 void *driverdata, unsigned int flags, isc_mem_t *mctx,
		 dns_sdbimplementation_t **sdbimp);
/*%<
 * Register a simple database driver for the database type 'drivername',
 * implemented by the functions in '*methods'.
 *
 * sdbimp must point to a NULL dns_sdbimplementation_t pointer.  That is,
 * sdbimp != NULL && *sdbimp == NULL.  It will be assigned a value that
 * will later be used to identify the driver when deregistering it.
 *
 * The name server will perform lookups in the database by calling the
 * function 'lookup', passing it a printable zone name 'zone', a printable
 * domain name 'name', and a copy of the argument 'dbdata' that
 * was potentially returned by the create function.  The 'dns_sdblookup_t'
 * argument to 'lookup' and 'authority' is an opaque pointer to be passed to
 * ns_sdb_putrr().
 *
 * The lookup function returns the lookup results to the name server
 * by calling ns_sdb_putrr() once for each record found.  On success,
 * the return value of the lookup function should be ISC_R_SUCCESS.
 * If the domain name 'name' does not exist, the lookup function should
 * ISC_R_NOTFOUND.  Any other return value is treated as an error.
 *
 * Lookups at the zone apex will cause the server to also call the
 * function 'authority' (if non-NULL), which must provide an SOA record
 * and NS records for the zone by calling ns_sdb_putrr() once for each of
 * these records.  The 'authority' function may be NULL if invoking
 * the 'lookup' function on the zone apex will return SOA and NS records.
 *
 * The allnodes function, if non-NULL, fills in an opaque structure to be
 * used by a database iterator.  This allows the zone to be transferred.
 * This may use a considerable amount of memory for large zones, and the
 * zone transfer may not be fully RFC1035 compliant if the zone is
 * frequently changed.
 *
 * The create function will be called for each zone configured
 * into the name server using this database type.  It can be used
 * to create a "database object" containing zone specific data,
 * which can make use of the database arguments specified in the
 * name server configuration.
 *
 * The destroy function will be called to free the database object
 * when its zone is destroyed.
 *
 * The create and destroy functions may be NULL.
 *
 * If flags includes DNS_SDBFLAG_RELATIVEOWNER, the lookup and authority
 * functions will be called with relative names rather than absolute names.
 * The string "@" represents the zone apex in this case.
 *
 * If flags includes DNS_SDBFLAG_RELATIVERDATA, the rdata strings may
 * include relative names.  Otherwise, all names in the rdata string must
 * be absolute.  Be aware that if relative names are allowed, any
 * absolute names must contain a trailing dot.
 *
 * If flags includes DNS_SDBFLAG_THREADSAFE, the driver must be able to
 * handle multiple lookups in parallel.  Otherwise, calls into the driver
 * are serialized.
