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.

.br type: the type value of the rr type .br 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.

.br descriptor: for an rr type .br 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.

.br descriptor: for an rr type .br 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.

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