ares_parse_soa_reply - Parse a reply to a DNS query of type SOA

#include <ares.h>

int ares_parse_soa_reply(const unsigned char* abuf, int alen,
 struct ares_soa_reply** soa_out);

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;
};

ares_parse_soa_reply can return any of the following values:

15 ARES_SUCCESS The response was successfully parsed.

15 ARES_EBADRESP The response was malformatted.

15 ARES_ENODATA The response did not contain an answer to the query.

15 ARES_ENOMEM Memory was exhausted.

This function was first introduced in c-ares version 1.9.0. ares_query (3) ares_free_data (3)
