Get number of data types registered for this simulation, including built-in types
int_T ssGetNumDataTypes(SimStruct *S)
SSimStruct representing an S-Function block.
An int_T value indicating the number of registered data
types.
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, see ssGetInputPortDataType.
Note
S-functions register their data types in their implementations of the
mdlInitializeSizes callback function. Therefore, to
ensure that this macro returns an accurate count, your S-function should invoke
it only after the point in the simulation at which the Simulink® engine invokes the mdlInitializeSizes callback
function.
For more information about using custom data types in S-functions, see Configure Custom Data Types.
