vkGetSemaphoreWin32HandleKHR

To export a Windows handle representing the payload of a semaphore, call:

VkResult vkGetSemaphoreWin32HandleKHR(
    VkDevice device,
    const VkSemaphoreGetWin32HandleInfoKHR* pGetWin32HandleInfo,
    HANDLE* pHandle);

• device is the logical device that created the semaphore being exported.
• pGetWin32HandleInfo is a pointer to a VkSemaphoreGetWin32HandleInfoKHR structure containing parameters of the export operation.
• pHandle will return the Windows handle representing the semaphore state.

For handle types defined as NT handles, the handles returned by vkGetSemaphoreWin32HandleKHR are owned by the application. To avoid leaking resources, the application must release ownership of them using the CloseHandle system call when they are no longer needed.

Exporting a Windows handle from a semaphore may have side effects depending on the transference of the specified handle type, as described in Importing Semaphore Payloads.
