#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
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:
- 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.
