I was reaching a similar conclusion Currently I have a void pointer to the struct with the members I mentioned
I can get char[100] pointerToStruct fromCString and I can get the int with pointerToStruct getHandle integerAt: 101 size:4 signed: false so if I want to pass the address of the pointer to my YourStruct instance will I have to initialize with YourStruct fromHandler: (pointerToStruct getHandle) is this a correct and safe way to pass the address ?
