# vkGetPhysicalDeviceExternalBufferProperties(3) Manual Page

## Name

vkGetPhysicalDeviceExternalBufferProperties - Query external handle types supported by buffers

Loading… please wait.

## C Specification

To query the external handle types supported by buffers, call:

    // Provided by VK_VERSION_1_1
    void vkGetPhysicalDeviceExternalBufferProperties(
        VkPhysicalDevice                            physicalDevice,
        const VkPhysicalDeviceExternalBufferInfo*   pExternalBufferInfo,
        VkExternalBufferProperties*                 pExternalBufferProperties);

or the equivalent command

    // Provided by VK_KHR_external_memory_capabilities
    void vkGetPhysicalDeviceExternalBufferPropertiesKHR(
        VkPhysicalDevice                            physicalDevice,
        const VkPhysicalDeviceExternalBufferInfo*   pExternalBufferInfo,
        VkExternalBufferProperties*                 pExternalBufferProperties);

## Parameters

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

- `pExternalBufferInfo` is a pointer to a VkPhysicalDeviceExternalBufferInfo structure describing the parameters that would be consumed by vkCreateBuffer.

- `pExternalBufferProperties` is a pointer to a VkExternalBufferProperties structure in which capabilities are returned.

## Description

Valid Usage (Implicit)

- VUID-vkGetPhysicalDeviceExternalBufferProperties-physicalDevice-parameter
  `physicalDevice` must be a valid VkPhysicalDevice handle

- VUID-vkGetPhysicalDeviceExternalBufferProperties-pExternalBufferInfo-parameter
  `pExternalBufferInfo` must be a valid pointer to a valid VkPhysicalDeviceExternalBufferInfo structure

- VUID-vkGetPhysicalDeviceExternalBufferProperties-pExternalBufferProperties-parameter
  `pExternalBufferProperties` must be a valid pointer to a VkExternalBufferProperties structure
