+    try
+    {
+        ...
+    }
+    catch (css::uno::RuntimeException &)
+    {
+        // you ought not handle RuntimeExceptions:

+    @endcode
+
+    Restrictions:
+    - use only for caught C++-UNO exceptions (UNOIDL defined)
+    - only as first statement in a catch block!
+    - don't do a C++ rethrow (throw;) after you have called this function
+    - call getCaughtException() just once in your catch block!
+      (function internally uses a C++ rethrow)
+
+    @return
+              caught UNO exception
+
+    @attention Caution!
+              This function is limited to the same C++ compiler runtime library.
+              E.g. for MSVC, this means that the catch handler code (the one
+              that calls getCaughtException()) needs to use the very same
+              C++ runtime library, e.g. msvcrt.dll as cppuhelper, e.g.
+              cppuhelper3MSC.dll and the bridge library, e.g. msci_uno.dll.
+              This is the case if all of them are compiled with the same
+              compiler version.
+              Background: The msci_uno.dll gets a rethrown exception out
+              of the internal msvcrt.dll thread local storage (tls).
+              Thus you _must_ not use this function if your code needs to run
+              in newer UDK versions without being recompiled, because those
+              newer UDK (-> OOo versions) potentially use newer C++ runtime
+              libraries which most often become incompatible!
+
+              But this function ought to be usable for most OOo internal C++-UNO
+              development, because the whole OOo code base is compiled using the
+              same C++ compiler (and linking against one runtime library).
