# vkGetPhysicalDeviceExternalFenceProperties(3) Manual Page

## Name

vkGetPhysicalDeviceExternalFenceProperties - Function for querying external fence handle capabilities.

## C Specification

Fences may support import and export of their payload to external handles. To query the external handle types supported by fences, call:

    void vkGetPhysicalDeviceExternalFenceProperties(
        VkPhysicalDevice                            physicalDevice,
        const VkPhysicalDeviceExternalFenceInfo*    pExternalFenceInfo,
        VkExternalFenceProperties*                  pExternalFenceProperties);

or the equivalent command

    void vkGetPhysicalDeviceExternalFencePropertiesKHR(
        VkPhysicalDevice                            physicalDevice,
        const VkPhysicalDeviceExternalFenceInfo*    pExternalFenceInfo,
        VkExternalFenceProperties*                  pExternalFenceProperties);

## Parameters

- `physicalDevice` is the physical device from which to query the fence capabilities.

- `pExternalFenceInfo` is a pointer to a VkPhysicalDeviceExternalFenceInfo structure describing the parameters that would be consumed by vkCreateFence.

- `pExternalFenceProperties` is a pointer to a VkExternalFenceProperties structure in which capabilities are returned.

## Description

Valid Usage (Implicit)

- `physicalDevice` must be a valid `VkPhysicalDevice` handle

- `pExternalFenceInfo` must be a valid pointer to a valid `VkPhysicalDeviceExternalFenceInfo` structure

- `pExternalFenceProperties` must be a valid pointer to a `VkExternalFenceProperties` structure
