ARES_EXPAND_NAME(3)					     Library Functions Manual					       ARES_EXPAND_NAME(3)

NAME

       ares_expand_name - Expand a DNS-encoded domain name

SYNOPSIS

       #include <ares.h>

       int ares_expand_name(const unsigned char *encoded,
       const unsigned char *abuf, int alen, char **s,
	    long *enclen)

DESCRIPTION

       The  ares_expand_name function converts a DNS-encoded domain name to a dot-separated C string.  The argument encoded gives the beginning of
       the encoded domain name, 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 name is stored in the variable pointed to by enclen so that  the  caller  can  advance
       past the encoded domain name to read further data in the message.

RETURN VALUES

       ares_expand_name can return any of the following values:

       ARES_SUCCESS   Expansion of the encoded name succeeded.

       ARES_EBADNAME  The encoded domain name was malformed and could not be expanded.

       ARES_ENOMEM    Memory was exhausted.
