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
