DESCRIPTION

       ldns_rr_descriptor
              Contains all information about resource record types.

              This structure contains, for all rr types, the rdata fields that
              are defined.
              struct ldns_struct_rr_descriptor
              {
                   Type of the RR that is described here:
                   ldns_rr_type    _type;
                   Textual name of the RR type.:
                   const char *_name;
                   Minimum number of rdata fields in the RRs of this type.:
                   uint8_t     _minimum;
                   Maximum number of rdata fields in the RRs of this type.:
                   uint8_t     _maximum;
                   Wireformat specification for the  rr,  i.e.  the  types  of
              rdata fields in their respective order.:
                   const ldns_rdf_type *_wireformat;
                   Special rdf types:
                   ldns_rdf_type _variable;
                   Specifies  whether  compression  can  be used for dnames in
              this RR type.:
                   ldns_rr_compress _compress;
                   The  number  of  DNAMEs  in  the  _wireformat  string,  for
              parsing.:
                   uint8_t _dname_count;
              };
              typedef struct ldns_struct_rr_descriptor ldns_rr_descriptor;

       ldns_rr_descript() returns the resource record descriptor for the given
              rr type.

              type: the type value of the rr type
              Returns the ldns_rr_descriptor for this type

       ldns_rr_descriptor_minimum() returns the minimum number of rdata fields
              of the rr type this descriptor describes.

              descriptor: for an rr type
              Returns the minimum number of rdata fields

       ldns_rr_descriptor_maximum() returns the maximum number of rdata fields
              of the rr type this descriptor describes.

              descriptor: for an rr type
              Returns the maximum number of rdata fields

       ldns_rr_descriptor_field_type() returns the  rdf  type  for  the  given
              rdata field number of the rr type for the given descriptor.

              descriptor: for an rr type
              field: the field number
              Returns the rdf type for the field
