| 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). |
