SYNOPSIS

#include <ldns/ldns.h>
const ldns_rr_descriptor* ldns_rr_descript(uint16_t type);

tor);

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 pars‐
ing.:
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
