I would like to gain some insight into how UPI/OPI works. Any chance of that? Not in order to write directly to that API, but I guess understanding how it works may enable us to write more efficient Pro*C or OCI programs or even a better understanding of the internal workings of Oracle. It is a pretty common misconception to believe that OCI is the native Oracle API.

Are there any "public" information about UPI/OPI available?
