# VkExternalFenceFeatureFlagBits(3) Manual Page

## Name

VkExternalFenceFeatureFlagBits - Bitfield describing features of an external fence handle type

Loading… please wait.

## C Specification

Bits which may be set in VkExternalFenceProperties::`externalFenceFeatures`, indicating features of a fence external handle type, are:

    // Provided by VK_VERSION_1_1
    typedef enum VkExternalFenceFeatureFlagBits {
        VK_EXTERNAL_FENCE_FEATURE_EXPORTABLE_BIT = 0x00000001,
        VK_EXTERNAL_FENCE_FEATURE_IMPORTABLE_BIT = 0x00000002,
      // Provided by VK_KHR_external_fence_capabilities
        VK_EXTERNAL_FENCE_FEATURE_EXPORTABLE_BIT_KHR = VK_EXTERNAL_FENCE_FEATURE_EXPORTABLE_BIT,
      // Provided by VK_KHR_external_fence_capabilities
        VK_EXTERNAL_FENCE_FEATURE_IMPORTABLE_BIT_KHR = VK_EXTERNAL_FENCE_FEATURE_IMPORTABLE_BIT,
    } VkExternalFenceFeatureFlagBits;

or the equivalent

    // Provided by VK_KHR_external_fence_capabilities
    typedef VkExternalFenceFeatureFlagBits VkExternalFenceFeatureFlagBitsKHR;

## Description

- `VK_EXTERNAL_FENCE_FEATURE_EXPORTABLE_BIT` specifies handles of this type can be exported from Vulkan fence objects.

- `VK_EXTERNAL_FENCE_FEATURE_IMPORTABLE_BIT` specifies handles of this type can be imported to Vulkan fence objects.
