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,

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;
};

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.
