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
