51    the specified buffers.  Returns a Bool indicating whether the
52    demangled failed or not.  A failure can occur because the prefix
53    isn't recognised, the internal Z-escaping is wrong, or because one
54    or the other (or both) of the output buffers becomes full.  Passing
55    'so' as NULL is acceptable if the caller is only interested in the
56    function name part. */
