The +VK_NN_vi_surface+ extension is an instance extension.
|
|
It provides a mechanism to create a slink:VkSurfaceKHR object (defined by
|
|
the +VK_KHR_surface+ extension) associated with an
|
|
code:nn::code:vi::code:Layer.

|
=== Issues
|
|
|
|
1) Does VI need a way to query for compatibility between a particular
|
|
physical device (and queue family?) and a specific VI display?
|
|
|
|
*RESOLVED*: No.
|
|
It is currently always assumed that the device and display will always be
|
|
compatible.
|
|
|
|
2) slink:VkViSurfaceCreateInfoNN::pname:pWindow is intended to store an
|
|
code:nn::code:vi::code:NativeWindowHandle, but its declared type is a bare
|
|
code:void* to store the window handle.
|
|
Why the discrepancy?
|
|
|
|
*RESOLVED*: It is for C compatibility.
|
|
The definition for the VI native window handle type is defined inside the
|
|
nn::vi C++ namespace.
|
|
This prevents its use in C source files.
|
|
nn::vi::NativeWindowHandle is always defined to be void*, so this
|
|
extension uses void* to match.
