* Checks that the <systemitem class="library">libxfce4panel</systemitem> library |

* the constants #LIBXFCE4PANEL_MAJOR_VERSION, #LIBXFCE4PANEL_MINOR_VERSION and |
|||
* #LIBXFCE4PANEL_MICRO_VERSION as the three arguments to this function; that produces |

* <systemitem class="library">libxfce4panel</systemitem> the extension was |
|||
* compiled against. |

* Return value: %NULL if the library is compatible with the given version, |
