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
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
