Updates for Windows 8.1: Windows 8.1 introduces a number of updates and improvements to the pointer input APIs. See API changes for Windows 8.1 for more info.If you're new to developing apps using JavaScript: Have a look through these topics to get familiar with the technologies discussed ...
Oh, fair point... I'll see about making the change now to put the vptr after the base (I expect this'll be easy enough, and can flip back/forth in this review if folks have opinions). How hard would this be to revisit in future? Seems easy enough - don't have a stable ABI, ...
Another common use for pointers to pointers is to facilitate dynamically allocated multidimensional arrays (see 17.12 -- Multidimensional C-style Arrays for a review of multidimensional arrays). Unlike a two dimensional fixed array, which can easily be declared like this: int array[10][5]; Copy ...

Thetypeidof an object is setafterthe objects constructor has executed. If there are base classes, thetypeidfor an object may be set multiple times, after each base class initialization. We will use the classes defined in Example 23.1 to demonstrate that calling avirtualfunction from a constructor...
the next WG21 plenary and hopefully will be voted into the C++23 draft. One interesting question came up during wording review. We discovered that, because an assumed expression is odr-used, it can trigger template instantiations and lambda captures, which in turn can change the ABI. Consider...
Smart pointers, however, are not the best place to implement COW, because smart pointers cannot differentiate between calls to const and non-const member functions of the pointee object. Here is an example: template <class T> class SmartPtr { public: T* operator->() { return pointee_; }...
We begin with a review of function pointers. In C, and consequently in C++, a function pointer calledmy_func_ptrthat points to a function taking anintand achar *and returning afloat, is declared like this: C++ float(*my_func_ptr)(int,char*);//To make it more understandable, I strong...
So if "Generic<Programming>" were a soap opera, this episode is going to shoo the villain away. To remind us who the villain is, let's review the previous episode [1]. (By the way, call it author lock-in, but the rest of this article assumes you have given at least an in-the...
Raw addresses (including ordinary pointers) cannot be assigned directly to smart pointers. You also need to include the <memory> header to use this template. Take the example of a simple pointer to an integer. To use such a pointer to allocate a new integer at runtime, you might use the...
