Not all class types need to be passed by reference (such asstd::string_view, which is normally passed by value). And you may be wondering why we don’t just pass everything by reference. In this section (which is optional reading), we discuss the cost of pass by value vs pass by ...
I have read that the only way to pass by reference with a function is if you pass a handle. Is there a matlab call to get the "handle" of a variable or structure?댓글 수: 0 댓글을 달려면 로그인하십시오....

C functions often return data in input arguments passed by reference. MATLAB creates additional output arguments to return these values. Input arguments ending inPtrorPtrPtrare also listed as outputs. For an example of MATLAB function signatures, seeShared Library shrlibsample. ...
I am having doubts about the function vector.push_back( T& x), in the documentation i am guessing that it is pass by reference because of the argument (T& x) but it doesnt seemed to work for me that way. For instance: #include "ExObj.h" #include <vector> #include <iostream> usi...
使用scoped_ptr 或者 ScopedVector,它们可以使用来管理所拥有的非引用计数的堆分配对象。 不拥有对象的时候 使用raw pointer 或者 WeakPtr。如果其它代码拥有对象,但是你需要知道这个对象是否已经被销毁,就使用 WeakPtr,当所关联的对象被销毁的时候 WeakPtr 会自动被置空。你可以通过 WeakPtr.get 方法获得关联对象的指...
