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

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 (Implicit)
  • VUID-vkGetPhysicalDeviceExternalImageFormatPropertiesNV-physicalDevice-parameter
    physicalDevice must be a valid VkPhysicalDevice handle

  • VUID-vkGetPhysicalDeviceExternalImageFormatPropertiesNV-format-parameter
    format must be a valid VkFormat value

  • 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
    pExternalImageFormatProperties must be a valid pointer to a VkExternalImageFormatPropertiesNV structure
