Hi,
this is the answer for a similar question I once asked Niklas:
Find the function name in sc/source/core/src/compiler.src, the
corresponding OpCode value in sc/inc/opcode.hxx, and look in
ScInterpreter::Interpret (sc/source/core/tool/interpr4.cxx) which
method is called for the OpCode. Add-In functions are separate, but
that's how you can find any built-in function's implementation.
Niklas
Hope this is helpful. Otherwise we will have to wait for Niklas' response.

Thank you all for the responses!
I've put together a small document (temporary link:
http://www.utsc.utoronto.ca/~04grycwo/overview.pdf) that outlines some
thoughts in terms of how I see this going, and a few potential
strategies.
Here's a quick summary:
1. Creating an R package that communicates directly with OpenOffice
and allows the passing of commands back and forth.
2. Doing the above with a TCP/IP connection instead.
3. Macros - sub-optimal in my opinion, but can be done.
I downloaded and started playing with OO source code. You're right in
saying
the documentation isn't the greatest, though I can see why: there's a lot
here. I think I'm getting the hang of it all, but just had some
questions:
1. Using the wiki, I learned how to modify current functions, and
exploring the code shows me where add-ins are placed and how they
look. I
was wondering, however, where do function names get stored? Again, I
see the
interpX.cxx but those function names are not the same as the ones I
call from Calc -- how does Calc know what to call?
I guess what I am trying to get at is, how can I add functions to Calc
through the source code? All the tutorials I've found are for add-ins.
2. From your perspectives, should this be considered an add-in or
directly coded into the "sc" folder? Is there any other area of the
source
code I should be working in?
3. Any thoughts on the TCP/IP versus package-to-OO communication
mentioned above? I think it might be a bit beyond the scope of the
summer
project, but I'd be happy to try to tackle it if there's interest.
I just finished my last exam for this school year on Friday at 4 pm,
so I'll
be working on this pretty much full-time now. You can expect to hear a
lot
more compared to what you've been hearing so far. :)
Thank you,
Wojciech
