Replacement Name: int64

Name for int64 data type in generated code

Model Configuration Pane: Code Generation / Data Type Replacement

Description

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

• 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.
