DESCRIPTION

33       ldns_rr_descriptor
34              struct to hold the whole set of rd_fields.
35
36              How does the whole rdata_field list look. This is called
37              the rdata in dns speak.
38              struct ldns_struct_rr_descriptor
39              {
40                   RR type:
41                   uint16_t    _type;
42                   Textual name.:
43                   const char *_name;
44                   Minimum number of RDATA FIELDs.:
45                   uint8_t     _minimum;
46                   Maximum number of RDATA FIELDs.:
47                   uint8_t     _maximum;
48                   wireformat specification for the rr:
49                   const ldns_rdf_type *_wireformat;
50                   Special rdf types:
51                   ldns_rdf_type _variable;
52                   Specifies whether compression can be used:
53                   ldns_rr_compress _compress;
54              };
55              typedef struct ldns_struct_rr_descriptor ldns_rr_descriptor;
56
57       ldns_rr_descript() returns the resource record descriptor for the given
58              rr type.
59
60              type: the type value of the rr type
61              Returns the ldns_rr_descriptor for this type
62
63       ldns_rr_descriptor_minimum() returns the minimum number of rdata fields
64              of the rr type this descriptor describes.
65
66              descriptor: for an rr type
67              Returns the minimum number of rdata fields
68
69       ldns_rr_descriptor_maximum() returns the maximum number of rdata fields
70              of the rr type this descriptor describes.
71
72              descriptor: for an rr type
73              Returns the maximum number of rdata fields
74
75       ldns_rr_descriptor_field_type() returns the  rdf  type  for  the  given
76              rdata field number of the rr type for the given descriptor.
77
78              descriptor: for an rr type
79              field: the field number
80              Returns the rdf type for the field
