WebJan 25, 2024 · I’ll start with a simple case: producing a safe array of bytes from C++ code. This safe array can be passed as an output parameter in a COM interface method or C-interface DLL function. A safe array is typically referenced via a pointer to its descriptor, which translates to SAFEARRAY* in C++ code. Web2 days ago · 1)I want to ask that how does this free all 400 bytes (in my case) is freed because ptr only contains address of one byte in the memory and also I have not passed any other argument specifying the size of the dynamic array so that it may run a loop and frees all the bytes. 2)And if I do ptr++; free (ptr); then what will happen.
