This chapter serves as an introduction to the APIs used in RT-LAB. The API provides a set of functions, constants, error codes and structures. You may use these functions and constants to perform various tasks such as creating your own GUI to interact with the simulation, creating test automation scripts using Python, for example or integrating RT-LAB with other software.
All API C functions have the “Opal” prefix in their name. However, for specific language such as Python, the prefix has been removed because the functions are grouped inside a module or a class. For instance, OpalCommand becomes Command in Python. All functions will be referred to without the “Opal” prefix in this chapter.
