# vkGetBufferMemoryRequirements(3) Manual Page

## Name

vkGetBufferMemoryRequirements - Returns the memory requirements for specified Vulkan object

Loading… please wait.

## C Specification

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

    // Provided by VK_VERSION_1_0
    void vkGetBufferMemoryRequirements(
        VkDevice                                    device,
        VkBuffer                                    buffer,
        VkMemoryRequirements*                       pMemoryRequirements);

## Parameters

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

- `buffer` is the buffer to query.

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

## Description

Valid Usage (Implicit)

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

- VUID-vkGetBufferMemoryRequirements-buffer-parameter
  `buffer` must be a valid VkBuffer handle

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

- VUID-vkGetBufferMemoryRequirements-buffer-parent
  `buffer` must have been created, allocated, or retrieved from `device`
