ssGetDataTypeZero

Get the zero representation of a data type

Syntax

void *ssGetDataTypeZero(SimStruct *S, DTypeId id)

Arguments

S

SimStruct representing an S-Function block.

id

ID of a data type.

Returns

A pointer (void *) to the zero representation of the data type specified by id, if id is valid and the data type's size has been set. Otherwise, returns NULL and reports an error.

Description

Use to obtain the zero representation of a data type.

    Note:   Because this macro reports any error that occurs, you do not need to use ssSetErrorStatus to report the error.

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.

Languages

C, C++

Example

The following example gets the zero representation of a custom data type.

const void *myZero = ssGetDataTypeZero(S, id);
if(myZero == NULL) return;
