This option instructs the Zephyr kernel to call the 'int main(void)' |

instead of the 'void main(void)', which is the default main() type |

for Zephyr. |

C++ does not allow the main() to be defined with 'void' return type, |

and any applications defining its main() in a C++ source file must |
|
enable this option. |
