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;
