ARES_PARSE_PTR_REPLY(3)     Library Functions Manual	 ARES_PARSE_PTR_REPLY(3)

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

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.

SEE ALSO
