--
To create a sname:VkSurfaceKHR object for a Fuchsia ImagePipe, call:
include::{generated}/api/protos/vkCreateImagePipeSurfaceFUCHSIA.txt[]
* pname:instance is the instance to associate with the surface.
* pname:pCreateInfo is a pointer to an instance of the
slink:VkImagePipeSurfaceCreateInfoFUCHSIA structure containing
parameters affecting the creation of the surface object.
* pname:pAllocator is the allocator used for host memory allocated for the
surface object when there is no more specific allocator available (see
<<memory-allocation,Memory Allocation>>).
* pname:pSurface points to a slink:VkSurfaceKHR handle in which the
created surface object is returned.

The sname:VkImagePipeSurfaceCreateInfoFUCHSIA structure is defined as:
include::{generated}/api/structs/VkImagePipeSurfaceCreateInfoFUCHSIA.txt[]
* pname:sType is the type of this structure.
* pname:pNext is `NULL` or a pointer to an extension-specific structure.
* pname:flags is reserved for future use.
* pname:imagePipeHandle is a code:zx_handle_t referring to the ImagePipe
to associate with the surface.
.Valid Usage
****
* [[VUID-VkImagePipeSurfaceCreateInfoFUCHSIA-imagePipeHandle-00000]]
pname:imagePipeHandle must: be a valid code:zx_handle_t

On Fuchsia, the surface pname:currentExtent is the special value
[eq]#(0xFFFFFFFF, 0xFFFFFFFF)#, indicating that the surface size will be
determined by the extent of a swapchain targeting the surface.
