35 * Examine the NSEC, NSEC3PARAM and privatetype RRsets at the apex of the
36 * database to determine which of NSEC or NSEC3 chains we are currently
37 * maintaining.  In normal operations only one of NSEC or NSEC3 is being
38 * maintained but when we are transitiong between NSEC and NSEC3 we need
39 * to update both sets of chains.  If 'privatetype' is zero then the
40 * privatetype RRset will not be examined.

42 * Requires:
43 * \li	'db' is valid.
44 * \li	'version' is valid or NULL.
45 * \li	'build_nsec' is a pointer to a isc_boolean_t or NULL.
46 * \li	'build_nsec3' is a pointer to a isc_boolean_t or NULL.
