Writing S-Functions

ssGetNumDataTypes

Get number of data types registered for this simulation, including built-in types.

Syntax

• int_T ssGetNumDataTypes(SimStruct *S)
  

Arguments

S
   SimStruct representing an S-Function block.

Description

Returns 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.

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 Simulink invokes the mdlInitializeSizes callback function.
