<br>
I can't give you much info about this.<br>
<br>
I don't _think_ you can get the macro name directly. A couple of months ago I wanted to see if a AST element was inside a assert macro or not.. but was told that there is no direct way to find this out.
<br>
<br>
I believe you could do it in some "hacky" way though. For instance by looking at the data that is used to output raw source code in error messages. Maybe there is a better way.<br>
<br>
Best regards,<br>
