I've been reading through the wave docs, it looks very impressive. I was wondering, is it possible to use Wave to extract all the macro/class/function definitions with their respective line numbers from a source file?

Partly. You can use Wave to extract macro definitions from the sources, but not to extract function/class definitions. For doing that you'll need to implement your own parser on top of Wave which extracts the required information from the token stream Wave is generating. Remember, Wave is just a preprocessor. It's almost the same as if you're trying to invoke your favorite compile in preprocessor mode (gcc -E or cl -P).

I noticed the mention of include paths etc however, does this mean that just throwing random source files from a large source tree at Wave, with no regard for whether or not all the types in it will be defined, is going to result in it throwing exceptions?

No. It will act on symbols, regardless whether these are types, function names or plain identifiers. The only thing it will do is to recognise macro definitions et.al. and to expand those when referenced in the source code. Wave throws exceptions on preprocessing errors only, i.e. wrong macro parameter counts or similar. HTH Regards Hartmut
