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.
