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

       #include <ares.h>

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

       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

       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.
