VOTELearn How to Use “Allowing Move Constructors to Throw [Noexcept]” For Windows Development With C++Builder
Pabitra Dash
The C++11 standard provides an alternative to std::move, which is std::move_if_noexcept, in order to solve some problematic interaction between move constructors, templates and certain standard library member functions. std::move_if_noexcept(x) grants permission to move x unless… … Read more

Learn How To Use C++ Extending Sizeof For Windows Development
Pabitra Dash
Given some class C with a data member m, the current standard makes it ill-formed to refer to m in sizeof expressions without providing an object. For example, uses such as sizeof(C::m) (outside of C) or sizeof(m) (in a static member of C) are ill-formed…. … Read more

Learn How To Use C++ Explicit Virtual Overrides In Windows Development
Pabitra Dash
Regarding virtual overrides, C++11 tends to tighten the rules, so as to detect some problems that often arise. In order to achieve this goal C++11 introduces two new contextual keywords: final specifies that a method cannot… … Read more

Learn An Efficient Way to Use C++ Extern Templates For Robust Windows Development
Pabitra Dash
Extern templates is a feature supported by both BCC32 and the Clang-enhanced C++ compilers. Using extern templates thus reduces both compilation time and the size of the compiled module. This feature is part of the new C++11… … Read more

Learn How to Use C++ Bidirectional Fences For Windows Development With C++Builder
Pabitra Dash
A memory fence/barrier is a class of instructions that enforces memory loads/stores occur in expected order. Different from high level mutexes and atomics, memory fences are hardware dependent. C++11 improves the support for bidirectional fences…. … Read more
