Reserved names

Avoid name conflicts with custom code

Model Configuration Pane: Code Generation / Identifiers

Description

Enter the names of variables or functions in the generated code that match the names of variables or functions specified in custom code.

Settings

{} (default) | array

This action changes the names of variables or functions in the generated code to avoid name conflicts with identifiers in custom code. Reserved names must be shorter than 256 characters. For example, it does not change these names:

  • data with a non-auto storage class

  • function names that you specify using function prototype control

  • bus object element names

  • Simulink functions with global scope

  • user-specified subsystem function names

Tips

  • Do not enter code generator keywords since these names cannot be changed in the generated code. For a list of keywords to avoid, see Reserved Keywords.

  • Start each reserved name with a letter or an underscore to prevent error messages.

  • Each reserved name must contain only letters, numbers, or underscores.

  • Separate the reserved names using commas or spaces.

  • You can also specify reserved names by using the command line:

    config_param_object.set_param('ReservedNameArray', {'abc','xyz'})

    where config_param_object is the object handle to the model settings in the Configuration Parameters dialog box.
