Replacement Name: int8

Name for int8 data type in generated code

Model Configuration Pane: Code Generation / Data Type Replacement


The Replacement Name: int8 parameter specifies the name to use for the built-in data type int8 in the generated code.


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


no default

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

  • int8_T if Data type replacement is Use coder typedefs.

  • int8_t 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.

  • The Simulink Name built-in data type name.

To use a Simulink.AliasType object:

  • Set the BaseType object property to int8.

  • 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 the Simulink Name, in the Replacement Name column, specify int8.

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.
