## Name

VkFenceGetWin32HandleInfoKHR - Structure describing a Win32 handle fence export operation

Loading… please wait.

## C Specification

The `VkFenceGetWin32HandleInfoKHR` structure is defined as:

    // Provided by VK_KHR_external_fence_win32
    typedef struct VkFenceGetWin32HandleInfoKHR {
        VkStructureType                      sType;
        const void*                          pNext;
        VkFence                              fence;
        VkExternalFenceHandleTypeFlagBits    handleType;
    } VkFenceGetWin32HandleInfoKHR;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `fence` is the fence from which state will be exported.

- `handleType` is a VkExternalFenceHandleTypeFlagBits value specifying the type of handle requested.

## Description

The properties of the handle returned depend on the value of `handleType`. See VkExternalFenceHandleTypeFlagBits for a description of the properties of the defined external fence handle types.

Valid Usage

- VUID-VkFenceGetWin32HandleInfoKHR-handleType-01448
  `handleType` must have been included in VkExportFenceCreateInfo::`handleTypes` when the `fence`’s current payload was created

- VUID-VkFenceGetWin32HandleInfoKHR-handleType-01449
  If `handleType` is defined as an NT handle, vkGetFenceWin32HandleKHR must be called no more than once for each valid unique combination of `fence` and `handleType`

- VUID-VkFenceGetWin32HandleInfoKHR-fence-01450
  `fence` must not currently have its payload replaced by an imported payload as described below in Importing Fence Payloads unless that imported payload’s handle type was included in VkExternalFenceProperties::`exportFromImportedHandleTypes` for `handleType`

- VUID-VkFenceGetWin32HandleInfoKHR-handleType-01451
  If `handleType` refers to a handle type with copy payload transference semantics, `fence` must be signaled, or have an associated fence signal operation pending execution

- VUID-VkFenceGetWin32HandleInfoKHR-handleType-01452
  `handleType` must be defined as an NT handle or a global share handle

Valid Usage (Implicit)

- VUID-VkFenceGetWin32HandleInfoKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_FENCE_GET_WIN32_HANDLE_INFO_KHR`

- VUID-VkFenceGetWin32HandleInfoKHR-pNext-pNext
  `pNext` must be `NULL`

- VUID-VkFenceGetWin32HandleInfoKHR-fence-parameter
  `fence` must be a valid VkFence handle

- VUID-VkFenceGetWin32HandleInfoKHR-handleType-parameter
  `handleType` must be a valid VkExternalFenceHandleTypeFlagBits value
