NAME
       ares_parse_ptr_reply - Parse a reply to a DNS query of type PTR into a hostent

SYNOPSIS
       #include <ares.h>

       int ares_parse_ptr_reply(const unsigned char *abuf, int alen,
	    const void *addr, int addrlen, int family,
       struct hostent **host);

DESCRIPTION
       The  ares_parse_ptr_reply function parses the response to a query of type PTR into a struct hostent.  The parameters abuf and alen give the
       contents of the response.  The parameters addr, addrlen, and family specify which address was queried for; they are not used to verify  the
       response,  merely  used	to  fill  in  the address of the struct hostent.  The resulting struct hostent is stored in allocated memory and a
       pointer to it stored into the variable pointed to by host.  It is the caller's responsibility to free the resulting  host  structure  using
       ares_free_hostent(3) when it is no longer needed.

RETURN VALUES
       ares_parse_ptr_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.
