C Specification

Bits which may be set in VkExternalSemaphoreProperties::externalSemaphoreFeatures, specifying the features of an external semaphore handle type, are:

// Provided by VK_VERSION_1_1
typedef enum VkExternalSemaphoreFeatureFlagBits {
    VK_EXTERNAL_SEMAPHORE_FEATURE_EXPORTABLE_BIT = 0x00000001,
    VK_EXTERNAL_SEMAPHORE_FEATURE_IMPORTABLE_BIT = 0x00000002,
  // Provided by VK_KHR_external_semaphore_capabilities
    VK_EXTERNAL_SEMAPHORE_FEATURE_EXPORTABLE_BIT_KHR = VK_EXTERNAL_SEMAPHORE_FEATURE_EXPORTABLE_BIT,
  // Provided by VK_KHR_external_semaphore_capabilities
    VK_EXTERNAL_SEMAPHORE_FEATURE_IMPORTABLE_BIT_KHR = VK_EXTERNAL_SEMAPHORE_FEATURE_IMPORTABLE_BIT,
} VkExternalSemaphoreFeatureFlagBits;

or the equivalent

// Provided by VK_KHR_external_semaphore_capabilities
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.
