Thanks, that was what I needed to get going.
Cheers

I'm trying to use booost.wave to parse some C headers and generate code for each function declaration found.
How would you write code that identifies all function declarations?
Is there any higher level structure that helps me finding this or do I need to create some state machine that matches the pattern for a function declaration from what's found in the token iterator?
Wave is a tokenizing preprocessor. That means all it can do is to return the recognized C++ tokens as seen in the input stream. In order to make some sense out of the token stream you need to write a parser matching the input you're looking for. You might want to look at one of Wave's examples, Hannibal, which is a partial C++ parser written using Spirit V1.8. In your case a much simpler grammar should be sufficient, though, as you're looking for function declarations only. Another pointer could be: http://gsd.web.elte.hu/contents/articles/gpce06.pdf. Those guys were using Spirit/Wave to instrument C++ code for template metaprogramming debugging purposes.
