Question

I am making a simple byte buffer that stores its data in a char array acquired with new and I was just wondering if the memcpy and memmove functions would give me anything weird if used on memory acquired with new or is there anything you would recommend doing instead?

Answer 1

No, they are perfectly fine. new and malloc() are just two different ways in you can aquire memory on the heap (actually they are quite the same, because new uses malloc() under the hood in most implementations). As soon as you have a valid char* variable in your hand (allocated by new, malloc() or on the stack) it is just a pointer to memory, hence memcpy() and other functions from this family will work as expected.
