This is the documentation of the direct api that call intro prism that work and the exact way as prism it self. There is only a thin layer at the top that takes care of converting between internal values in the C API calls in form of a simple class structure. This is done in C++ library that is named DEBPrismLib. This api is then the one exposed to Python through the PyCXX library.
The name of the library is debprism so to use it, make sure you have the debprism.pyd module installed with its supporting prismdql9.dll and support files and a license file. With all in place you can start using the library by import debprism.
