* Searches DHCP network container for instances that match the query
* described by the combination of query and targetp. If the partial
* argument is true, then lookup operations that are unable to
* complete entirely are allowed (and considered successful). The
* query argument consists of 2 fields, each 16 bits long. The lower
* 16 bits selects which fields {client_id, flags, client_ip,
* server_ip, expiration, macro, or comment} of targetp are to be
* considered in the query. The upper 16 bits identifies whether a
* particular field value must match (bit set) or not match (bit
* clear). Bits 7-15 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
* returned. The recordsp argument is set to point to the resulting
* list of records; if recordsp is passed in as NULL then no records
* are actually returned. Note that these records are dynamically
* allocated, thus the caller is responsible for freeing them. The
* number of records found is returned in nrecordsp; a value of 0 means
* that no records matched the query.
