C Data and Function Interfaces

Map model data elements and functions to model-independent code definitions

To comply with code standards and guidelines, integrate generated code with external code, and address memory requirements, configure the representation of model data elements and entry-point functions for code generation. You configure model data elements and functions by mapping them to code definitions that are predefined by the product or created with the Embedded Coder Dictionary. For data elements, you also have the option of mapping them to code definitions created in packages with the Custom Storage Class Designer.

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