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,
    VK_EXTERNAL_FENCE_FEATURE_EXPORTABLE_BIT_KHR = VK_EXTERNAL_FENCE_FEATURE_EXPORTABLE_BIT,
    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.
