# vkGetDeviceImageSparseMemoryRequirements(3) Manual Page

## Name

vkGetDeviceImageSparseMemoryRequirements - Query the memory requirements for a sparse image

Loading… please wait.

## C Specification

To determine the sparse memory requirements for an image resource without creating an object, call:

    // Provided by VK_VERSION_1_3
    void vkGetDeviceImageSparseMemoryRequirements(
        VkDevice                                    device,
        const VkDeviceImageMemoryRequirements*      pInfo,
        uint32_t*                                   pSparseMemoryRequirementCount,
        VkSparseImageMemoryRequirements2*           pSparseMemoryRequirements);

or the equivalent command

    // Provided by VK_KHR_maintenance4
    void vkGetDeviceImageSparseMemoryRequirementsKHR(
        VkDevice                                    device,
        const VkDeviceImageMemoryRequirements*      pInfo,
        uint32_t*                                   pSparseMemoryRequirementCount,
        VkSparseImageMemoryRequirements2*           pSparseMemoryRequirements);

## Parameters

- `device` is the logical device intended to own the image.

- `pInfo` is a pointer to a VkDeviceImageMemoryRequirements structure containing parameters required for the memory requirements query.

- `pSparseMemoryRequirementCount` is a pointer to an integer related to the number of sparse memory requirements available or queried, as described below.

- `pSparseMemoryRequirements` is either `NULL` or a pointer to an array of `VkSparseImageMemoryRequirements2` structures.

## Description

Valid Usage (Implicit)

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

- VUID-vkGetDeviceImageSparseMemoryRequirements-pInfo-parameter
  `pInfo` must be a valid pointer to a valid VkDeviceImageMemoryRequirements structure

- VUID-vkGetDeviceImageSparseMemoryRequirements-pSparseMemoryRequirementCount-parameter
  `pSparseMemoryRequirementCount` must be a valid pointer to a `uint32_t` value

- VUID-vkGetDeviceImageSparseMemoryRequirements-pSparseMemoryRequirements-parameter
  If the value referenced by `pSparseMemoryRequirementCount` is not `0`, and `pSparseMemoryRequirements` is not `NULL`, `pSparseMemoryRequirements` must be a valid pointer to an array of `pSparseMemoryRequirementCount` VkSparseImageMemoryRequirements2 structures
