C++ - Function returning reference: Here, we will learn with a C++ program, how to return a reference from function? What is Function Returning Reference in C++? As we know that we can take only variable on the left side in C++ statements, we can also use a function on the left side...
pointer() == nullptr) PONDER_ERROR(NullObject(&uobj.getClass())); return uobj.ref<TTo>(); } }; // Specialisation for returning const references. template <typename TTo> struct ConvertArg<(int)ValueKind::User, const TTo&> { typedef const TTo& ReturnType; static ReturnType convert(const...
If I have a C function returning a mxArray pointer: mxArray* myCFunction(mxArray* args); Will then Matlab be responsible for deleting the object? What If the function returns a null pointer or the input arguments, is this forbidden, e.g.: mxArray* myCFunction(mxArray* args){ return ...

In this design it's easy to forget that the sqptr pointer is also a member variable of some other object, and can be deleted by this object, for example. Nevertheless returning a heap-allocated copy of a heap-allocated member variable from the member function is the direct way ...
