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
