vkGetBufferMemoryRequirements2(3)

# vkGetBufferMemoryRequirements2(3) Manual Page

## Name

vkGetBufferMemoryRequirements2 - Returns the memory requirements for specified Vulkan object

## C Specification

To determine the memory requirements for a buffer resource, call:

    // Provided by VK_VERSION_1_1
    void vkGetBufferMemoryRequirements2(
        VkDevice                                    device,
        const VkBufferMemoryRequirementsInfo2*      pInfo,
        VkMemoryRequirements2*                      pMemoryRequirements);

    // Provided by VK_KHR_get_memory_requirements2
    // Equivalent to vkGetBufferMemoryRequirements2
    void vkGetBufferMemoryRequirements2KHR(
        VkDevice                                    device,
        const VkBufferMemoryRequirementsInfo2*      pInfo,
        VkMemoryRequirements2*                      pMemoryRequirements);

## Parameters

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

- `pInfo` is a pointer to a VkBufferMemoryRequirementsInfo2 structure containing parameters required for the memory requirements query.

- `pMemoryRequirements` is a pointer to a VkMemoryRequirements2 structure in which the memory requirements of the buffer object are returned.

## Description

Valid Usage (Implicit)

- VUID-vkGetBufferMemoryRequirements2-device-parameter
  `device` must be a valid VkDevice handle

- VUID-vkGetBufferMemoryRequirements2-pInfo-parameter
  `pInfo` must be a valid pointer to a valid VkBufferMemoryRequirementsInfo2 structure

- VUID-vkGetBufferMemoryRequirements2-pMemoryRequirements-parameter
  `pMemoryRequirements` must be a valid pointer to a VkMemoryRequirements2 structure
