Get the zero representation of a data type
void *ssGetDataTypeZero(SimStruct *S, DTypeId id)
SimStruct representing an S-Function block.
ID of a data type.
A pointer (
void *) to the zero representation of the data type
id is valid and the data
type's size has been set. Otherwise, returns
NULL and reports an
Use to obtain the zero representation of a data type, which is the value that represents zero for the custom data type.
Because this macro reports any error that occurs, you do not need to use
ssSetErrorStatus to report the error.
For more information about using custom data types in S-functions, see Custom Data Types.
The following example gets the zero representation of a custom data type.
const void *myZero = ssGetDataTypeZero(S, id); if(myZero == NULL) return;
