To create a sname:VkSurfaceKHR object for a Win32 window, call:
|
|
|
|
include::../../api/protos/vkCreateWin32SurfaceKHR.txt[]
|
|
|
|
* pname:instance is the instance to associate the surface with.
|
|
* pname:pCreateInfo is a pointer to an instance of the
|
|
sname:VkWin32SurfaceCreateInfoKHR 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:VkWin32SurfaceCreateInfoKHR structure is defined as:
|
|
|
|
include::../../api/structs/VkWin32SurfaceCreateInfoKHR.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:hinstance and pname:hwnd are the Win32 code:HINSTANCE and
|
|
code:HWND for the window to associate the surface with.
|
|
|
|
.Valid Usage
|
|
****
|
|
* [[VUID-VkWin32SurfaceCreateInfoKHR-hinstance-01307]]
|
|
pname:hinstance must: be a valid Win32 code:HINSTANCE.
|
|
* [[VUID-VkWin32SurfaceCreateInfoKHR-hwnd-01308]]
|
|
pname:hwnd must: be a valid Win32 code:HWND.
|
|

|
|
|
|
With Win32, pname:minImageExtent, pname:maxImageExtent, and
|
|
pname:currentExtent must: always equal the window size.
|
|
|
|
The pname:currentExtent of a Win32 surface must: have both pname:width and
|
|
pname:height greater than 0, or both of them 0.
|
|
|
|
[NOTE]
|
|
.Note
|
|
====
|
|
Due to above restrictions, it is only possible to create a new swapchain on
|
|
this platform with pname:imageExtent being equal to the current size of the
|
|
window.
|
|
|
|
The window size may: become [eq]#(0, 0)# on this platform (e.g. when the
|
|
window is minimized), and so a swapchain cannot: be created until the size
|
|
changes.
