}; Now that we have a reference counting class, we will introduce this to our smart pointer class. We will maintain a pointer to classRCin ourSPclass and this pointer will be shared for all instances of the smart pointer which refers to the same pointer. For this to happen, we need t...
My implementation seems to be running almost as fast as raw pointers, which I think is a good sign. What worries me here is why Boost is running slower. Have I missed something in my implementation that is important and I might get into trouble for later? So the idea behind this is ma...
Pointer Arguments in C Functions Many functions in external libraries pass arguments by reference. When you pass by reference, you pass apointerto the value. In the function signature, pointer arguments have names ending inPtrandPtrPtr. Although MATLAB®does not support passing by reference, you...
