I was trying to write a package file in C for db2. But I was just wondering what all include files and functions can be used. I saw this example in this link by york university. It explains a lot but I don't know what resources are available in terms of include libraries and their functions.
Your help is highly appreciated.

Here's a link to the PDF manuals -- see the Application Development section.
