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.
