C Function Block Configuration

When to Use

• Calling or wrapping C/C++ code or libraries in Simulink
• Creating, configuring, or using a C Function block
• Integrating custom code, legacy code, or external C/C++ into a model
• Integrating a C++ class into a Simulink model or test bench
• Configuring inputs, outputs, or parameters for a C++ algorithm in a block

When NOT to Use

• Building general Simulink models without C/C++ integration
• MATLAB Function blocks (Embedded MATLAB) — those use MATLAB syntax, not C/C++
• Code generation workflows (Embedded Coder, Simulink Coder) — this skill is for simulation-time configuration only
