Answer by SmacL for Does C++ support 'finally' blocks? (And what's this 'RAII' I keep hearing about?)

FWIW, Microsoft Visual C++ does support try,finally and it has historically been used in MFC apps as a method of catching serious exceptions that would otherwise result in a crash. For example;

int CMyApp::Run() {    __try    {        int i = CWinApp::Run();        m_Exitok = MAGIC_EXIT_NO;        return i;    }    __finally    {        if (m_Exitok != MAGIC_EXIT_NO)            FaultHandler();    }}

I've used this in the past to do things like save backups of open files prior to exit. Certain JIT debugging settings will break this mechanism though.
