NAME

       ldns_rr_descriptor, ldns_rr_descript, ldns_rr_descriptor_minimum,
       ldns_rr_descriptor_maximum, ldns_rr_descriptor_field_type - rdata field descriptors

SYNOPSIS

       #include <stdint.h>
       #include <stdbool.h>

       #include <ldns/ldns.h>

       const ldns_rr_descriptor* ldns_rr_descript(uint16_t type);

       size_t ldns_rr_descriptor_minimum(const ldns_rr_descriptor *descriptor);

       size_t ldns_rr_descriptor_maximum(const ldns_rr_descriptor *descriptor);

       ldns_rdf_type ldns_rr_descriptor_field_type(const ldns_rr_descriptor *descriptor, size_t
       field);

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
