ARES_PARSE_A_REPLY(3)                       DragonFly Library Functions Manual


NAME

       ares_parse_a_reply - Parse a reply to a DNS query of type A


SYNOPSIS

       #include <ares.h>

       int ares_parse_a_reply(const unsigned char *abuf, int alen,
            struct hostent **host,
       struct ares_addrttl *addrttls, int *naddrttls);


DESCRIPTION

       The ares_parse_a_reply function parses the response to a query of type
       A into a struct hostent and/or an array of struct ares_addrttls.  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 host, if host is nonnull.  It is the caller's
       responsibility to free the resulting host structure using
       ares_free_hostent(3) when it is no longer needed.

       If addrttls and naddrttls are both nonnull, then up to *naddrttls
       struct ares_addrttl records are stored in the array pointed to by
       addrttls, and then *naddrttls is set to the number of records so
       stored.  Note that the memory for these records is supplied by the
       caller.


RETURN VALUES

       ares_parse_a_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.
