determine image capabilities compatible with external memory handle types.

C Specification

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

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

Description

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

Valid Usage (Implicit)

• physicalDevice must be a valid VkPhysicalDevice handle
• format must be a valid VkFormat value
• type must be a valid VkImageType value
• tiling must be a valid VkImageTiling value
• usage must be a valid combination of VkImageUsageFlagBits values
• usage must not be 0
• flags must be a valid combination of VkImageCreateFlagBits values
• externalHandleType must be a valid combination of VkExternalMemoryHandleTypeFlagBitsNV values
• pExternalImageFormatProperties must be a valid pointer to a VkExternalImageFormatPropertiesNV structure

Return Codes

On success, this command returns

• SUCCESS

On failure, this command returns

• ERROR_OUT_OF_HOST_MEMORY
• ERROR_OUT_OF_DEVICE_MEMORY
• ERROR_FORMAT_NOT_SUPPORTED
