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.
