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.
