C Specification

The VkExternalSemaphoreProperties structure is defined as:

// Provided by VK_VERSION_1_1
typedef struct VkExternalSemaphoreProperties {
    VkStructureType                       sType;
    void*                                 pNext;
    VkExternalSemaphoreHandleTypeFlags    exportFromImportedHandleTypes;
    VkExternalSemaphoreHandleTypeFlags    compatibleHandleTypes;
    VkExternalSemaphoreFeatureFlags       externalSemaphoreFeatures;
} VkExternalSemaphoreProperties;

or the equivalent

// Provided by VK_KHR_external_semaphore_capabilities
typedef VkExternalSemaphoreProperties VkExternalSemaphorePropertiesKHR;

Members

  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • exportFromImportedHandleTypes is a bitmask of VkExternalSemaphoreHandleTypeFlagBits specifying which types of imported handle handleType can be exported from.

  • compatibleHandleTypes is a bitmask of VkExternalSemaphoreHandleTypeFlagBits specifying handle types which can be specified at the same time as handleType when creating a semaphore.

  • externalSemaphoreFeatures is a bitmask of VkExternalSemaphoreFeatureFlagBits describing the features of handleType.

Description

If handleType is not supported by the implementation, then VkExternalSemaphoreProperties::externalSemaphoreFeatures will be set to zero.

Valid Usage (Implicit)

  • VUID-VkExternalSemaphoreProperties-sType-sType
    sType must be VK_STRUCTURE_TYPE_EXTERNAL_SEMAPHORE_PROPERTIES

  • VUID-VkExternalSemaphoreProperties-pNext-pNext
    pNext must be NULL
