ARES_EXPAND_NAME(3)					     Library Functions Manual					       ARES_EXPAND_NAME(3)

NAME

       ares_expand_string - Expand a length encoded string

SYNOPSIS

       #include <ares.h>

       int ares_expand_string(const unsigned char *encoded,
       const unsigned char *abuf, int alen, unsigned char **s,
	    long *enclen)

DESCRIPTION

       The ares_expand_string function converts a length encoded string to a NUL-terminated C string.  The argument encoded gives the beginning of
       the encoded string, and the arguments abuf and alen give the containing message buffer (necessary for the processing of indirection  point-
       ers  within the encoded domain name).  The result is placed in a NUL-terminated allocated buffer, a pointer to which is stored in the vari-
       able pointed to by s.  The length of the encoded string is stored in the variable pointed to by enclen so that the caller can advance  past
       the encoded string to read further data in the message.

RETURN VALUES

       ares_expand_string can return any of the following values:

       ARES_SUCCESS   Expansion of the encoded string succeeded.

       ARES_EBADSTR   The encoded string was malformed and could not be expanded.

       ARES_ENOMEM    Memory was exhausted.

NAME

       ares_parse_aaaa_reply - Parse a reply to a DNS query of type AAAA

SYNOPSIS

       #include <ares.h>

       int ares_parse_aaaa_reply(const unsigned char *abuf, int alen,
	    struct hostent **host,
       struct ares_addr6ttl *addrttls, int *naddrttls);

DESCRIPTION

       The  ares_parse_aaaa_reply  function  parses  the  response  to	a  query  of  type  AAAA  into	a struct hostent and/or an array of struct
       ares_addr6ttl.  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 variable 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_addr6ttl records are stored in the array pointed to by addrt-
       tls, 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_aaaa_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.
