VkPhysicalDeviceExternalFenceInfo

The VkPhysicalDeviceExternalFenceInfo structure is defined as:

typedef struct VkPhysicalDeviceExternalFenceInfo {
    VkStructureType sType;
    const void* pNext;
    VkExternalFenceHandleTypeFlagBits handleType;
} VkPhysicalDeviceExternalFenceInfo;

or the equivalent

typedef VkPhysicalDeviceExternalFenceInfo VkPhysicalDeviceExternalFenceInfoKHR;

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

sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_EXTERNAL_FENCE_INFO

VUID-VkPhysicalDeviceExternalFenceInfo-pNext-pNext

pNext must be NULL

VUID-VkPhysicalDeviceExternalFenceInfo-handleType-parameter

handleType must be a valid VkExternalFenceHandleTypeFlagBits value
