Same as @ref AutoFunctionTrace, but traces to @c stdlog. |

If you link to the library @c libmrwautofunctiontracestdlog using |

a linker option such as: @c -lmrwautofunctiontracestdlog and you |

must enable the GNU Compiler Collection specific function trace |
||||
feature with compile and link option @c -finstrument-functions |

then you get an automatical function trace, that traces to @c |

stdlog. You don't need to change a single line in your code! |
