## C Specification

The special queue family index `VK_QUEUE_FAMILY_FOREIGN_EXT` represents any queue external to the resource’s current Vulkan instance, regardless of the queue’s underlying physical device or driver version. This includes, for example, queues for fixed-function image processing devices, media codec devices, and display devices, as well as all queues that use the same underlying device group or physical device, and the same driver version as the resource’s VkDevice.
