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);


  • device is the logical device that created the fence.

  • pImportFenceWin32HandleInfo is a pointer to a VkImportFenceWin32HandleInfoKHR structure specifying the fence and import parameters.


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.
