/**
* libxfce4panel_check_version:

* @required_minor: the required minor version.
* @required_micro: the required micro version.
*
* Checks that the <systemitem class="library">libxfce4panel</systemitem> library
* in use is compatible with the given version. Generally you would pass in
* the constants #LIBXFCE4PANEL_MAJOR_VERSION, #LIBXFCE4PANEL_MINOR_VERSION and
* #LIBXFCE4PANEL_MICRO_VERSION as the three arguments to this function; that produces
* a check that the library in use is compatible with the version of
* <systemitem class="library">libxfce4panel</systemitem> the extension was
* compiled against.
*
* <example>
* <title>Checking the runtime version of the Libxfce4ui library</title>
* <programlisting>
* const gchar *mismatch;
* mismatch = libxfce4panel_check_version (LIBXFCE4PANEL_MAJOR_VERSION,

* LIBXFCE4PANEL_MICRO_VERSION);
* if (G_UNLIKELY (mismatch != NULL))
* g_error ("Version mismatch: %<!---->s", mismatch);
* </programlisting>
* </example>
*
* Return value: %NULL if the library is compatible with the given version,
* or a string describing the version mismatch. The returned
* string is owned by the library and must not be freed or
* modified by the caller.
