ares_parse_soa_reply - Man Page

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;

Return Values

ares_parse_soa_reply can return any of the following values:


The response was successfully parsed.


The response was malformatted.


The response did not contain an answer to the query.


Memory was exhausted.


This function was first introduced in c-ares version 1.9.0.
