accessing Userdata made by tolua++

[dawm@...]

Hi,
I want to get a list of attributes of a C struct added to Lua with tolua++.
For example:
struct testC
{
  int number;
  char* name;
}


In lua:
  my_s = function_returning_testC()
  print_fields(my_s)

On output:
my_s: testC
"int" "number"
"char*" "name"

Best regards
Nick
