The first, <function>sg_get_error</function> returns an sg_error code |

which relates to the last error generated by libstatgrab. This can be |

converted to a string by calling <function>sg_str_error</function> |

giving the sg_error code as an argument. Finally, an optional |

argument may be set when the error was generated. This can be |
