## Name

vkGetPhysicalDeviceExternalImageFormatPropertiesNV - Determine image capabilities compatible with external memory handle types

Loading… please wait.

## C Specification

To determine the image capabilities compatible with an external memory handle type, call:

    // Provided by VK_NV_external_memory_capabilities
    VkResult vkGetPhysicalDeviceExternalImageFormatPropertiesNV(
        VkPhysicalDevice                            physicalDevice,
        VkFormat                                    format,
        VkImageType                                 type,
        VkImageTiling                               tiling,
        VkImageUsageFlags                           usage,
        VkImageCreateFlags                          flags,
        VkExternalMemoryHandleTypeFlagsNV           externalHandleType,
        VkExternalImageFormatPropertiesNV*          pExternalImageFormatProperties);

## Parameters

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

- `format` is the image format, corresponding to VkImageCreateInfo::`format`.

- `type` is the image type, corresponding to VkImageCreateInfo::`imageType`.

- `tiling` is the image tiling, corresponding to VkImageCreateInfo::`tiling`.

- `usage` is the intended usage of the image, corresponding to VkImageCreateInfo::`usage`.

- `flags` is a bitmask describing additional parameters of the image, corresponding to VkImageCreateInfo::`flags`.

- `externalHandleType` is either one of the bits from VkExternalMemoryHandleTypeFlagBitsNV, or 0.

- `pExternalImageFormatProperties` is a pointer to a VkExternalImageFormatPropertiesNV structure in which capabilities are returned.

## Description

If `externalHandleType` is 0, `pExternalImageFormatProperties->imageFormatProperties` will return the same values as a call to vkGetPhysicalDeviceImageFormatProperties, and the other members of `pExternalImageFormatProperties` will all be 0. Otherwise, they are filled in as described for VkExternalImageFormatPropertiesNV.

Valid Usage

- VUID-vkGetPhysicalDeviceExternalImageFormatPropertiesNV-externalHandleType-07721
  `externalHandleType` must not have more than one bit set

Valid Usage (Implicit)

- VUID-vkGetPhysicalDeviceExternalImageFormatPropertiesNV-type-parameter
  `type` must be a valid VkImageType value

- VUID-vkGetPhysicalDeviceExternalImageFormatPropertiesNV-tiling-parameter
  `tiling` must be a valid VkImageTiling value

- VUID-vkGetPhysicalDeviceExternalImageFormatPropertiesNV-usage-parameter
  `usage` must be a valid combination of VkImageUsageFlagBits values

- VUID-vkGetPhysicalDeviceExternalImageFormatPropertiesNV-usage-requiredbitmask
  `usage` must not be `0`

- VUID-vkGetPhysicalDeviceExternalImageFormatPropertiesNV-flags-parameter
  `flags` must be a valid combination of VkImageCreateFlagBits values

- VUID-vkGetPhysicalDeviceExternalImageFormatPropertiesNV-externalHandleType-parameter
  `externalHandleType` must be a valid combination of VkExternalMemoryHandleTypeFlagBitsNV values

- VUID-vkGetPhysicalDeviceExternalImageFormatPropertiesNV-pExternalImageFormatProperties-parameter
