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
