NAME
ares_parse_soa_reply - Parse a reply to a DNS query of type SOA
SYNOPSIS
#include <ares.h>
int ares_parse_soa_reply(const unsigned char* abuf, int alen,
struct ares_soa_reply** soa_out);
DESCRIPTION
The ares_parse_soa_reply function parses the response to a query of
type SOA into a struct ares_soa_reply. The parameters abuf and alen
give the contents of the response. The result is stored in allocated
memory and a pointer to it stored into the variable pointed to by
soa_out. It is the caller's responsibility to free the resulting
soa_out structure when it is no longer needed using the function
ares_free_data(3).
The structure ares_soa_reply contains the following fields:
struct ares_soa_reply {
char *nsname;
char *hostmaster;
unsigned int serial;
unsigned int refresh;
unsigned int retry;
unsigned int expire;
unsigned int minttl;
};
RETURN VALUES
ares_parse_soa_reply can return any of the following values:
ARES_SUCCESS The response was successfully parsed.
ARES_EBADRESP The response was malformatted.
ARES_ENODATA The response did not contain an answer to the query.
ARES_ENOMEM Memory was exhausted.
AVAILABILITY
This function was first introduced in c-ares version 1.9.0.
