Get number of data types registered for this simulation, including built-in types
int_T ssGetNumDataTypes(SimStruct *S)
SimStruct representing an S-Function block.
int_T value indicating the number of registered
Use to obtain the number of data types registered for this simulation.
This includes all custom data types registered by custom S-Function
blocks and all built-in data types. For a list of built-in data types,
S-functions register their data types in their implementations
The Simulink Coder™ product does not support S-functions that contain custom data types. Attempting to generate code for a model that contains this macro results in an error.
