|
To create a sname:VkSurfaceKHR object for an code:nn::code:vi::code:Layer,
|
|
query the layer's native handle using
|
|
code:nn::code:vi::code:GetNativeWindow, and then call:
|
|
|
|
include::../../api/protos/vkCreateViSurfaceNN.txt[]
|
|
|
|
* pname:instance is the instance with which to associate the surface.
|
|
* pname:pCreateInfo is a pointer to an instance of the
|
|
sname:VkViSurfaceCreateInfoNN 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.
|
|
|
|
During the lifetime of a surface created using a particular
|
|
code:nn::code:vi::code:NativeWindowHandle any attempts to create another
|
|
surface for the same code:nn::code:vi::code:Layer and any attempts to
|
|
connect to the same code:nn::code:vi::code:Layer through other platform
|
|
mechanisms will have undefined: results.
|
|
|
|
If the native window is created with a specified size, pname:currentExtent
|
|
will reflect that size.
|
|
In this case, applications should use the same size for the swapchain's
|
|
pname:imageExtent.
|
|
Otherwise, the pname:currentExtent will have the special value
|
|
[eq]#(0xFFFFFFFF, 0xFFFFFFFF)#, indicating that applications are expected to
|
|
choose an appropriate size for the swapchain's pname:imageExtent (e.g., by
|
|
matching the result of a call to
|
|
code:nn::code:vi::code:GetDisplayResolution).

The sname:VkViSurfaceCreateInfoNN structure is defined as:
|
|
|
|
include::../../api/structs/VkViSurfaceCreateInfoNN.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:window is the code:nn::code:vi::code:NativeWindowHandle for the
|
|
code:nn::code:vi::code:Layer with which to associate the surface.
