NAME

ldns_rdf, ldns_rdf_type - rdata field type

SYNOPSIS

#include <stdint.h> #include <stdbool.h> #include <ldns/ldns.h>

DESCRIPTION

ldns_rdf Resource record data field. The data is a network ordered array of bytes, which size is specified by the (16-bit) size field. To correctly parse it, use the type specified in the (16-bit) type field with a value from \ref ldns_rdf_type. struct ldns_struct_rdf { The size of the data (in octets): size_t _size; The type of the data: ldns_rdf_type _type; Pointer to the data (raw octets): void *_data; }; typedef struct ldns_struct_rdf ldns_rdf; ldns_rdf_type The different types of RDATA fields. enum ldns_enum_rdf_type { none: LDNS_RDF_TYPE_NONE, domain name: LDNS_RDF_TYPE_DNAME, 8 bits: LDNS_RDF_TYPE_INT8, 16 bits: LDNS_RDF_TYPE_INT16, 32 bits: LDNS_RDF_TYPE_INT32, A record: LDNS_RDF_TYPE_A, AAAA record: LDNS_RDF_TYPE_AAAA, txt string: LDNS_RDF_TYPE_STR, apl data: LDNS_RDF_TYPE_APL, b32 string: LDNS_RDF_TYPE_B32_EXT, b64 string: LDNS_RDF_TYPE_B64, hex string: LDNS_RDF_TYPE_HEX, nsec type codes: LDNS_RDF_TYPE_NSEC, a RR type: LDNS_RDF_TYPE_TYPE, a class: LDNS_RDF_TYPE_CLASS, certificate algorithm: LDNS_RDF_TYPE_CERT_ALG, a key algorithm: LDNS_RDF_TYPE_ALG, unknown types: LDNS_RDF_TYPE_UNKNOWN, time (32 bits): LDNS_RDF_TYPE_TIME, period: LDNS_RDF_TYPE_PERIOD, tsig time 48 bits: LDNS_RDF_TYPE_TSIGTIME, /** Represents the Public Key Algorithm, HIT and Public Key fields for the HIP RR types.
