I'm developing a program that simulates game inputs. Using the SendInput() function of C ++. I have already been able to simulate keyboard inputs from the INPUT structure using the INPUT_KEYBOARD parameter, however I do not know how to use the INPUT_HARDWARE parameter to simulate an Xbox control, for example. I'm using the <Windows.h> library. Here are some links I'm using as a reference:
