 * considered in the query.  The upper 16 bits identifies whether a
 * particular field value must match (bit set) or not match (bit
 * clear).  Bits 2-15 in both 16 bit fields are currently unused, and
 * must be set to 0.  The count field specifies the maximum number of
 * matching records to return, or -1 if any number of records may be

 * list of records; if recordsp is passed in as NULL then no records
 * are actually returned. Note that these records are dynamically
