Replacement Name: char

Name for char data type in generated code

Model Configuration Pane: Code Generation / Data Type Replacement

Description

The Replacement Name: char parameter specifies the name to use for the built-in data type char 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:

• char_T if Data type replacement is Use coder typedefs.

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

You can specify a replacement name by using a Simulink.AliasType object:

• Set the BaseType object property to intn. n is the number of bits set for Configuration Parameters > Hardware Implementation > Number of bits: char.

• 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 object.

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.
