SYNOPSIS


#include <ares.h> 

int ares_parse_naptr_reply(const unsigned char* abuf, int alen, struct ares_naptr_reply** naptr_out);

DESCRIPTION

The ares_parse_naptr_reply function parses the response to a query of type NAPTR into a linked list of struct ares_naptr_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 naptr_out. It is the caller’s responsibility to free the resulting naptr_out structure when it is no longer needed using the function ares_free_data

The structure ares_naptr_reply contains the following fields:

struct ares_naptr_reply {
    struct ares_naptr_reply *next;
    unsigned char *flags;
    unsigned char *service;
    unsigned char *regexp;
    char *replacement;
    unsigned short order;
    unsigned short preference;
};

RETURN VALUES

ares_parse_naptr_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.
