C Specification
To import a fence payload from a Windows handle, call:
// Provided by VK_KHR_external_fence_win32
VkResult vkImportFenceWin32HandleKHR(
VkDevice device,
const VkImportFenceWin32HandleInfoKHR* pImportFenceWin32HandleInfo);
Parameters
-
device
is the logical device that created the fence. -
pImportFenceWin32HandleInfo
is a pointer to a VkImportFenceWin32HandleInfoKHR structure specifying the fence and import parameters.
Description
Importing a fence payload from Windows handles does not transfer ownership
of the handle to the Vulkan implementation.
For handle types defined as NT handles, the application must release
ownership using the CloseHandle
system call when the handle is no
longer needed.
Applications can import the same fence payload into multiple instances of Vulkan, into the same instance from which it was exported, and multiple times into a given Vulkan instance.
