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 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.
