# vkGetImageSparseMemoryRequirements2(3) Manual Page

## Name

vkGetImageSparseMemoryRequirements2 - Query the memory requirements for a sparse image

Loading… please wait.

## C Specification

To query sparse memory requirements for an image, call:

    // Provided by VK_VERSION_1_1
    void vkGetImageSparseMemoryRequirements2(
        VkDevice                                    device,
        const VkImageSparseMemoryRequirementsInfo2* pInfo,
        uint32_t*                                   pSparseMemoryRequirementCount,
        VkSparseImageMemoryRequirements2*           pSparseMemoryRequirements);

or the equivalent command

    // Provided by VK_KHR_get_memory_requirements2
    void vkGetImageSparseMemoryRequirements2KHR(
        VkDevice                                    device,
        const VkImageSparseMemoryRequirementsInfo2* pInfo,
        uint32_t*                                   pSparseMemoryRequirementCount,
        VkSparseImageMemoryRequirements2*           pSparseMemoryRequirements);

## Parameters

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

- `pInfo` is a pointer to a VkImageSparseMemoryRequirementsInfo2 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-vkGetImageSparseMemoryRequirements2-device-parameter
  `device` must be a valid VkDevice handle

- VUID-vkGetImageSparseMemoryRequirements2-pInfo-parameter
  `pInfo` must be a valid pointer to a valid VkImageSparseMemoryRequirementsInfo2 structure

- VUID-vkGetImageSparseMemoryRequirements2-pSparseMemoryRequirementCount-parameter
  `pSparseMemoryRequirementCount` must be a valid pointer to a `uint32_t` value

- VUID-vkGetImageSparseMemoryRequirements2-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
