[cfe-dev] Regarding clang-c and comments...

I'm writing a very simple c parser (dumps formatted symbols, something
similar to ctags but actually working) using clang-c, which is working well,
but I'm hoping to add some support for source comments in the code.
At the moment I'm using the clang-c subset for this, but there doesn't seem
to be any api for accessing comments; specifically CXCursorKind doesn't seem
to have a type for 'comment', and I've ended up doing something similar to:
for each cursor
get cursor info
save info (specifically, offset, filename, display name)
for each saved symbol:
find the closest previous symbol
walk backwards through the file from position of symbol -> position of
previous symbol looking for closest comment
This is quite annoying to do, and has a few problems (example: symbols with
no filename, unsaved files, large projects means loading every symbol into
Is there a to get comments as elements through to the visitor function?
If no in clang-c, then perhaps in the full clang api?
Finally, as a slightly better alternative, is there a way to query a cursor
to get the previous lexical cursor? At the very least this would save me
having to save the entire set of data in memory first..
Help much appreciated!
