# vkGetImageMemoryRequirements(3) Manual Page

## Name

vkGetImageMemoryRequirements - Returns the memory requirements for specified Vulkan object

Loading… please wait.

## C Specification

To determine the memory requirements for an image resource which is not created with the `VK_IMAGE_CREATE_DISJOINT_BIT` flag set, call:

    // Provided by VK_VERSION_1_0
    void vkGetImageMemoryRequirements(
        VkDevice                                    device,
        VkImage                                     image,
        VkMemoryRequirements*                       pMemoryRequirements);

## Parameters

- `device` is the logical device that owns the image.

- `image` is the image to query.

- `pMemoryRequirements` is a pointer to a VkMemoryRequirements structure in which the memory requirements of the image object are returned.

## Description

Valid Usage

- VUID-vkGetImageMemoryRequirements-image-01588
  `image` must not have been created with the `VK_IMAGE_CREATE_DISJOINT_BIT` flag set

- VUID-vkGetImageMemoryRequirements-image-04004
  If `image` was created with the `VK_EXTERNAL_MEMORY_HANDLE_TYPE_ANDROID_HARDWARE_BUFFER_BIT_ANDROID` external memory handle type, then `image` must be bound to memory

Valid Usage (Implicit)

- VUID-vkGetImageMemoryRequirements-device-parameter
  `device` must be a valid VkDevice handle

- VUID-vkGetImageMemoryRequirements-image-parameter
  `image` must be a valid VkImage handle

- VUID-vkGetImageMemoryRequirements-pMemoryRequirements-parameter
  `pMemoryRequirements` must be a valid pointer to a VkMemoryRequirements structure

- VUID-vkGetImageMemoryRequirements-image-parent
  `image` must have been created, allocated, or retrieved from `device`
