Replacement Name: int64

Name for int64 data type in generated code

Model Configuration Pane: Code Generation / Data Type Replacement


The Replacement Name: int64 parameter specifies the name to use for the built-in data type int64 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:

  • int64_T if Data type replacement is Use coder typedefs.

  • int64_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.NumericType object.

  • The Simulink Name built-in data type name.

To use a Simulink.NumericType object:

  • Set these properties:

    • DataTypeMode –– Fixed-point: binary point scaling

    • Signedness –– Signed

    • WordLength –– 64

    • IsAlias –– true

    • HeaderFile –– Name of header file that provides type definition.

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

To use the Simulink Name, in the Replacement Name column, specify int64.

An error occurs, if:

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

  • The object is Simulink.AliasType.
