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.
