# VkExportFenceCreateInfo(3) Manual Page

## Name

VkExportFenceCreateInfo - Structure specifying handle types that can be exported from a fence

Loading… please wait.

## C Specification

To create a fence whose payload can be exported to external handles, add a VkExportFenceCreateInfo structure to the `pNext` chain of the VkFenceCreateInfo structure. The `VkExportFenceCreateInfo` structure is defined as:

    // Provided by VK_VERSION_1_1
    typedef struct VkExportFenceCreateInfo {
        VkStructureType                   sType;
        const void*                       pNext;
        VkExternalFenceHandleTypeFlags    handleTypes;
    } VkExportFenceCreateInfo;

or the equivalent

    // Provided by VK_KHR_external_fence
    typedef VkExportFenceCreateInfo VkExportFenceCreateInfoKHR;

## Members

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

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

- `handleTypes` is a bitmask of VkExternalFenceHandleTypeFlagBits specifying one or more fence handle types the application can export from the resulting fence. The application can request multiple handle types for the same fence.

## Description

Valid Usage

- VUID-VkExportFenceCreateInfo-handleTypes-01446
  The bits in `handleTypes` must be supported and compatible, as reported by VkExternalFenceProperties

Valid Usage (Implicit)

- VUID-VkExportFenceCreateInfo-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_EXPORT_FENCE_CREATE_INFO`

- VUID-VkExportFenceCreateInfo-handleTypes-parameter
  `handleTypes` must be a valid combination of VkExternalFenceHandleTypeFlagBits values
