Data and Function Configuration

Configure code generation for data and functions to facilitate software integration

To generate code for rapid prototyping, configure the representation of model data elements for code generation. You configure model data elements by mapping them to code definitions (storage classes) that are predefined by the product.

For an introduction, see C Code Generation Configuration for Model Interface Elements.
