| 22 | Helper macro for argument checking in functions. First argument *func_name* is |
| 23 | the name of the function, other arguments are the names of the required |
| 24 | arguments to that function. The macro iterates through the list, and prints |
| 25 | and error message if not all arguments are defined. |
