The parameters +.IR addr , +.IR addrlen , +and +.I family +specify which address was queried for; they are not used to verify the +response, merely used to fill in the address of the +.BR "struct hostent" . +The resulting +.B struct hostent +is stored in allocated memory and a pointer to it stored into the +variable pointed to by +.IR host . +It is the caller's responsibility to free the resulting host structure +using +.BR ares_free_hostent (3) +when it is no longer needed. +.SH RETURN VALUES +.B ares_parse_ptr_reply +can return any of the following values: +.TP 15 +.B ARES_SUCCESS +The response was successfully parsed. +.TP 15 +.B ARES_EBADRESP +The response was malformatted. +.TP 15 +.B ARES_ENODATA +The response did not contain an answer to the query. +.TP 15 +.B ARES_ENOMEM +Memory was exhausted. +.SH SEE ALSO +.BR ares_gethostbyaddr (3), +.BR ares_free_hostent (3) +.SH AUTHOR +Greg Hudson, MIT Information Systems +.br +Copyright 1998 by the Massachusetts Institute of Technology. -- cgit v1.2.3
