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 indirec-
       tion pointers within the encoded domain name).  The result is placed in	a  NUL-terminated
       allocated  buffer,  a  pointer  to  which  is stored in the variable 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.
