# VkExternalSemaphoreFeatureFlagBits(3) Manual Page

## Name

VkExternalSemaphoreFeatureFlagBits - Bitfield describing features of an external semaphore handle type

## C Specification

Possible values of VkExternalSemaphoreProperties::`externalSemaphoreFeatures`, specifying the features of an external semaphore handle type, are:

    typedef enum VkExternalSemaphoreFeatureFlagBits {
        VK_EXTERNAL_SEMAPHORE_FEATURE_EXPORTABLE_BIT = 0x00000001,
        VK_EXTERNAL_SEMAPHORE_FEATURE_IMPORTABLE_BIT = 0x00000002,
        VK_EXTERNAL_SEMAPHORE_FEATURE_EXPORTABLE_BIT_KHR = VK_EXTERNAL_SEMAPHORE_FEATURE_EXPORTABLE_BIT,
        VK_EXTERNAL_SEMAPHORE_FEATURE_IMPORTABLE_BIT_KHR = VK_EXTERNAL_SEMAPHORE_FEATURE_IMPORTABLE_BIT,
        VK_EXTERNAL_SEMAPHORE_FEATURE_FLAG_BITS_MAX_ENUM = 0x7FFFFFFF
    } VkExternalSemaphoreFeatureFlagBits;

or the equivalent

    typedef VkExternalSemaphoreFeatureFlagBits VkExternalSemaphoreFeatureFlagBitsKHR;

## Description

- `VK_EXTERNAL_SEMAPHORE_FEATURE_EXPORTABLE_BIT` specifies that handles of this type can be exported from Vulkan semaphore objects.

- `VK_EXTERNAL_SEMAPHORE_FEATURE_IMPORTABLE_BIT` specifies that handles of this type can be imported as Vulkan semaphore objects.
