C Specification

The VkPhysicalDeviceExternalFenceInfo structure is defined as:

// Provided by VK_VERSION_1_1
typedef struct VkPhysicalDeviceExternalFenceInfo {
    VkStructureType                      sType;
    const void*                          pNext;
    VkExternalFenceHandleTypeFlagBits    handleType;
} VkPhysicalDeviceExternalFenceInfo;


  • sType is a VkStructureType value identifying this structure.

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

  • handleType is a VkExternalFenceHandleTypeFlagBits value specifying an external fence handle type for which capabilities will be returned.



Handles of type VK_EXTERNAL_FENCE_HANDLE_TYPE_SYNC_FD_BIT generated by the implementation may represent either Linux Sync Files or Android Fences at the implementation’s discretion. Applications should only use operations defined for both types of file descriptors, unless they know via means external to Vulkan the type of the file descriptor, or are prepared to deal with the system-defined operation failures resulting from using the wrong type.

Valid Usage (Implicit)
  • VUID-VkPhysicalDeviceExternalFenceInfo-sType-sType

  • VUID-VkPhysicalDeviceExternalFenceInfo-pNext-pNext
    pNext must be NULL

  • VUID-VkPhysicalDeviceExternalFenceInfo-handleType-parameter
    handleType must be a valid VkExternalFenceHandleTypeFlagBits value
