the syntax for the pointer to pointer is a bit weird

You are right, there was a missing const, added.

| ## Error code collection | ||
|
|
||
| If you want to enable the error code collection (for example in a separate executable), you also need to declare the preprocessor constant `ERROR_MESSAGE_COLLECTION` **before** including the main header file `error_message.h`. |

Add that you can also set it globally via compiler flags

and we probably should have an example project, where we show, how to use these flags.

- First question, is this the format the crawler expects.
- Second, for the error code, we need to replace underscore with dash.

is there any reason that the parameter names of the macro are shortened

Should we maybe add the variables itself also to the namespace, such that we don't pollute the default namespace to much.

Do we check somewhere the structure of the error code?

I think, we need an example, how this looks after all Macros are replaced.

We need to replace underscore with dashes in the error code.
