[cedet-semantic] semanticdb questions

[Stuart P. <st...@pi...>]

Hi,

I'm trying to get semanticdb to do lookups across multiple directories 
in a given project, and am somewhat stymied by the docs. I have a few 
questions:

1. Once a cache file is created, semantic maintains it by updating from 
changed buffers at exit. Does semantic also check file dates on cached 
files, so that files changed outside of emacs (say, from CVS) stay 
updated as well?

2. In the semanticdb-find-nonterminal-by-* functions, is the DATABASES 
argument a list of file paths to cache files? Or are they database lisp 
objects?

3. In semanticdb-find-nonterminal-by-function, is the FUNCTION arg a 
string? or a semantic object?

4. Finally, I'm having trouble dealing with the return objects of 
semanticdb-find-nonterminal functions, which seem often to be the entire 
cache, or at least the entire entry for a given file. What's the overall 
  approach recommended for locating the actual textual extent of a tag 
definition, using these functions?

Thanks,
Stuart Popejoy
