ldns(3) Library Functions Manual ldns(3) NAME ldns_rr_descriptor, ldns_rr_descript, ldns_rr_descriptor_minimum, ldns_rr_descriptor_maximum, ldns_rr_descriptor_field_type - rdata field de- scriptors 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 *de- scriptor, 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 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 AUTHOR The ldns team at NLnet Labs.
