New Index

Hello,

I am trying to create a new index for high multi-dimensional indexing.
The index I'm trying to use in PR-Tree ( www.cs.duke.edu/~yike/prtree/
).

I have created a new source file in "src/backend/access/" and for now
I have created the empty functions: build, insert, vacuum, etc... I
believe that this has to be done in C. Then I ran "/src/include/
catalog/unused_oids" to find the unused oids, and then i added the
oids to the functions in the source "file /src/include/catalog/
pg_proc.h". I re-ran initdb and inserted the functions in pg_am table.

Now obviously I have to add the proper code to the functions, but the
version of the code I have for the PR-Tree is in C++. Is there a way
to implement the functions using the existing PR-Tree code in C++?

Thanks for your help.

Regards,
Alan
