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  en-
     coded  string,  and the arguments abuf and alen give the containing message
     buffer (necessary for the processing of indirection pointers within the en-
     coded 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.
