# VkPhysicalDeviceHostImageCopyFeaturesEXT(3) Manual Page

## Name

VkPhysicalDeviceHostImageCopyFeaturesEXT - Structure indicating support for copies to or from images from host memory

Loading… please wait.

## C Specification

The `VkPhysicalDeviceHostImageCopyFeaturesEXT` structure is defined as:

    // Provided by VK_EXT_host_image_copy
    typedef struct VkPhysicalDeviceHostImageCopyFeaturesEXT {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           hostImageCopy;
    } VkPhysicalDeviceHostImageCopyFeaturesEXT;

## Members

This structure describes the following feature:

## Description

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `hostImageCopy` indicates that the implementation supports copying from host memory to images using the vkCopyMemoryToImageEXT command, copying from images to host memory using the vkCopyImageToMemoryEXT command, and copying between images using the vkCopyImageToImageEXT command.

If the `VkPhysicalDeviceHostImageCopyFeaturesEXT` structure is included in the `pNext` chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. `VkPhysicalDeviceHostImageCopyFeaturesEXT` can also be used in the `pNext` chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceHostImageCopyFeaturesEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_HOST_IMAGE_COPY_FEATURES_EXT`
