关于__try __except中的GetExceptionCode和GetExceptionInformation宏？
网上看到这两个宏只能在紧跟__except后的括号中使用，否则结果不能保证。但我发现GetExceptionCode可以在__except后的语句块使用，并且得到了ExceptionCode。请问这样用有什么副作用吗？

C/C++ code

    int        *error = 0;    ULONG    errcode = 0;    __try{        *error = 0;    }    __except( EXCEPTION_EXECUTE_HANDLER/*AnalysisException(GetExceptionInformation())*/ ){        //===============================================================        //= = Safe place.        errcode = GetExceptionCode();                    switch ( errcode ){        case EXCEPTION_ACCESS_VIOLATION:            MessageBox( NULL, "非法访问！", "Hint", MB_OK );            break;        case EXCEPTION_INT_DIVIDE_BY_ZERO:            MessageBox( NULL, "除0错误！", "Hint", MB_OK );            break;        case EXCEPTION_SINGLE_STEP:            MessageBox( NULL, "单步中断！", "Hint", MB_OK );            break;        case EXCEPTION_BREAKPOINT:            MessageBox( NULL, "断点异常！", "Hint", MB_OK );            break;        default:            MessageBox( NULL, "程序异常！", "Hint", MB_OK );            break;        }    }
