C Specification
To import a semaphore payload from a Windows handle, call:
VkResult vkImportSemaphoreWin32HandleKHR(
VkDevice device,
const VkImportSemaphoreWin32HandleInfoKHR* pImportSemaphoreWin32HandleInfo);
Parameters
-
device
is the logical device that created the semaphore. -
pImportSemaphoreWin32HandleInfo
is a pointer to a VkImportSemaphoreWin32HandleInfoKHR structure specifying the semaphore and import parameters.
Description
Importing a semaphore 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 semaphore payload into multiple instances of Vulkan, into the same instance from which it was exported, and multiple times into a given Vulkan instance.
