C Specification

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

// Provided by VK_VERSION_1_3
void vkGetDeviceImageMemoryRequirements(
    VkDevice                                    device,
    const VkDeviceImageMemoryRequirements*      pInfo,
    VkMemoryRequirements2*                      pMemoryRequirements);

or the equivalent command

// Provided by VK_KHR_maintenance4
void vkGetDeviceImageMemoryRequirementsKHR(
    VkDevice                                    device,
    const VkDeviceImageMemoryRequirements*      pInfo,
    VkMemoryRequirements2*                      pMemoryRequirements);

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.

  • pMemoryRequirements is a pointer to a VkMemoryRequirements2 structure in which the memory requirements of the image object are returned.

Description

Valid Usage (Implicit)

  • VUID-vkGetDeviceImageMemoryRequirements-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkGetDeviceImageMemoryRequirements-pInfo-parameter
    pInfo must be a valid pointer to a valid VkDeviceImageMemoryRequirements structure

  • VUID-vkGetDeviceImageMemoryRequirements-pMemoryRequirements-parameter
    pMemoryRequirements must be a valid pointer to a VkMemoryRequirements2 structure
