class S { public: S() = default; private: S(const S&) = default; }; void f(const S&); // pass S by reference int main() { S s; f(s); } 弃用属性化 ATL 代码支持(默认开启等级 1 (/W1)) 以前版本的编译器支持属性化 ATL 代码。 由于下一阶段将删除从Visual Studio 2008 开始的...
ctypes exports the byref() function which is used to pass parameters by reference. The same effect can be achieved with the pointer() function, although pointer() does a lot more work since it constructs a real pointer object, so it is faster to use byref() if you don’t need the poi...

shared_ptr unique_ptr weak_ptr auto_ptr(被 C++11 弃用) Class shared_ptr 实现共享式拥有(shared ownership)概念。多个智能指针指向相同对象,该对象和其相关资源会在 “最后一个 reference 被销毁” 时被释放。为了在结构较复杂的情景中执行上述工作,标准库提供 weak_ptr、bad_weak_ptr 和 enable_shared_from...

C functions often return data in input arguments passed by reference. MATLAB creates additional output arguments to return these values. Input arguments ending in Ptr or PtrPtr are also listed as outputs. For an example of MATLAB function signatures, see Shared Library shrlibsample. Guidelines for...
