C Specification
To export a Windows handle representing the state of a fence, call:
VkResult vkGetFenceWin32HandleKHR(
VkDevice device,
const VkFenceGetWin32HandleInfoKHR* pGetWin32HandleInfo,
HANDLE* pHandle);
Parameters
-
device
is the logical device that created the fence being exported. -
pGetWin32HandleInfo
is a pointer to a VkFenceGetWin32HandleInfoKHR structure containing parameters of the export operation. -
pHandle
will return the Windows handle representing the fence state.
Description
For handle types defined as NT handles, the handles returned by
vkGetFenceWin32HandleKHR
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 fence may have side effects depending on the transference of the specified handle type, as described in Importing Fence Payloads.
