Catching all unhandled C++ exceptions?

Question

Is there some way to catch exceptions which are otherwise unhandled (including those thrown outside the catch block)?

I'm not really concerned about all the normal cleanup stuff done with exceptions, just that I can catch it, write it to log/notify the user and exit the program, since the exceptions in these casese are generaly fatal, unrecoverable errors.

something like:

global_catch() {     MessageBox(NULL,L"Fatal Error", L"A fatal error has occured. Sorry for any inconvience", MB_ICONERROR);     exit(-1); } global_catch(Exception *except) {     MessageBox(NULL,L"Fatal Error", except->ToString(), MB_ICONERROR);     exit(-1); }

This can be used to catch unexpected exceptions.

catch (...) {     std::cout << "OMG! an unexpected exception has been caught" << std::endl; } 

Without a try catch block, I don't think you can catch exceptions, so structure your program so the exception thowing code is under the control of a try/catch.
