DESCRIPTION
       ldnsrrdescriptor
              Contains all information about resource record types.

              This structure contains, for all rr types, the rdata fields that
              are defined.
              struct ldnsstructrrdescriptor
              {
                   Type of the RR that is described here:
                   ldnsrrtype    type;
                   Textual name of the RR type.:
                   const char *name;
                   Minimum number of rdata fields in the RRs of this type.:
                   uint8t     minimum;
                   Maximum number of rdata fields in the RRs of this type.:
                   uint8t     maximum;
                   Wireformat specification for the  rr,  i.e.  the  types  of
              rdata fields in their respective order.:
                   const ldnsrdftype *wireformat;
                   Special rdf types:
                   ldnsrdftype variable;
                   Specifies  whether  compression  can  be used for dnames in
              this RR type.:
                   ldnsrrcompress compress;
                   The number of DNAMEs in the wireformat string,  for  pars‐
              ing.:
                   uint8t dnamecount;
              };
              typedef struct ldnsstructrrdescriptor ldnsrrdescriptor;

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

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

       ldnsrrdescriptorminimum() 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

       ldnsrrdescriptormaximum() 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

       ldnsrrdescriptorfieldtype() 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
