How do I Insert records from within sql 2000 extended stored procedures?

I am trying to find out how to insert records into tables from within a sql 2000 extended stored procedure. If you know how please let me know.

Can you explain what you mean by sql 2000 extended procs? Which one are you talking about? Can you show some code?

The following is the visual studio 6 C++ function that is linked to the extended stored procedure that I created. What I want it to do is write to tables in the db also. I have no idea how to do that as I've seen no examples.
