DESCRIPTION

24       Converts a possibly ACE encoded domain name in  UTF-32  format  into  a
25       UTF-32  string (punycode decoding). The output buffer will be zero-ter‐
26       minated and must be deallocated by the caller.
27
28        output may be NULL to test lookup of  input without allocating memory.
