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).
