ARES_PARSE_A_REPLY(3)					 ARES_PARSE_A_REPLY(3)

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 vari‐
       able  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.
