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
