Hello,
It is said that vkGetInstanceProcAddr can be used to get any API function pointer
Then what is the difference between
vkGetInstanceProcAddr(inst, “some api”) , where inst may be nullptr
and
vkGetDeviceProcAddr(device, “some api”)

The difference is that the device function saves a dispatch. The instance one has to make sure that your function calls will work with all devices, the device one gives you function pointers that only work with that device.
