VkPhysicalDeviceLayeredApiKHR

The list of possible API implementations of a layered implementation underneath the Vulkan physical device, as returned in VkPhysicalDeviceLayeredApiPropertiesKHR::layeredAPI, are:

typedef enum VkPhysicalDeviceLayeredApiKHR {
    VK_PHYSICAL_DEVICE_LAYERED_API_VULKAN_KHR = 0,
    VK_PHYSICAL_DEVICE_LAYERED_API_D3D12_KHR = 1,
    VK_PHYSICAL_DEVICE_LAYERED_API_METAL_KHR = 2,
    VK_PHYSICAL_DEVICE_LAYERED_API_OPENGL_KHR = 3,
    VK_PHYSICAL_DEVICE_LAYERED_API_OPENGLES_KHR = 4,
} VkPhysicalDeviceLayeredApiKHR;

• VK_PHYSICAL_DEVICE_LAYERED_API_VULKAN_KHR - the device implements the Vulkan API.
• VK_PHYSICAL_DEVICE_LAYERED_API_D3D12_KHR - the device implements the D3D12 API.
• VK_PHYSICAL_DEVICE_LAYERED_API_METAL_KHR - the device implements the Metal API.
• VK_PHYSICAL_DEVICE_LAYERED_API_OPENGL_KHR - the device implements the OpenGL API.
• VK_PHYSICAL_DEVICE_LAYERED_API_OPENGLES_KHR - the device implements the OpenGL ES API.
