  --dst-file "path/to/dst_file" \
  --src-function "SRC_FUNCTION" \
  --src-file "path/to/src_file"
```

## Parameters

- `dst_function_name` (positional): Destination function name.
- `--dst-file`: File path where the destination function is defined (optional).
- `--src-function`: Source function name (optional; default `LLVMFuzzerTestOneInput`).
