Replacement Name: boolean

Name for boolean data type in generated code

Model Configuration Pane: Code Generation / Data Type Replacement

Description

The Replacement Name: boolean parameter specifies the name to use for the built-in data type boolean in the generated code.

Dependencies

To enable this parameter, select the Specify custom data type names parameter.

Settings

no default

If a value is not specified, the code generator uses the Code Generation Name:

  • boolean_T if Data type replacement is Use coder typedefs.

  • bool if Data type replacement is Use C data types with fixed-width integers.

You can specify a replacement name by using one of the following:

  • A Simulink.AliasType object.

  • A Simulink.NumericType object.

  • The Simulink Name built-in data type name.

To use a Simulink.AliasType object:

  • Set the BaseType object property to boolean, uint8 , int8, or intn, where n is the number of bits set for Configuration Parameters > Hardware Implementation > Number of bits: int.

  • Set the HeaderFile object property to the name of the header file that provides the type definition.

  • In the Replacement Name column, specify the object name.

To use a Simulink.NumericType object:

  • Set the DataTypeMode object property to Boolean.

  • Set the HeaderFile object property to the name of the header file that provides the type definition.

  • In the Replacement Name column, specify the name of the Simulink.NumericType object.

To use the Simulink Name:

  • In the Replacement Name column, specify uint8, int8, or intn, where n is the number of bits set for Configuration Parameters > Hardware Implementation > Number of bits: int.

For ERT S-functions, the replacement data type can be only an 8-bit integer, int8, or uint8.

An error occurs, if:

  • A replacement data type specification is inconsistent with the Simulink Name data type.

  • The Simulink.AliasType object has the Data scope parameter set to Exported.
