# halt

[Valid for](../../../Shared/FeatureAvailability.md):  CANoe DE • CANoe:lite DE • CANoe4SW DE • CANoe4SW:lite DE

## Function Syntax

```plaintext theme={null}
void halt();
```

## Description

The function stops both the debugged program as well as the simulation. The debugger window opens and the halt() command is displayed. The function thus creates a breakpoint while simultaneously interrupting the measurement in simulated mode (also for test modules). The simulation can be continued with `<F9>`. For usage in Real Mode, it is only activated for test modules and test configurations otherwise the halt instruction is ignored.

## Parameters

## Return Values

## Example

```plaintext theme={null}
on key 'h'
{
  halt(); 
  // Stops execution of the simulation in Simulation mode
}
```
