vkGetDeviceBufferMemoryRequirements(3)

# vkGetDeviceBufferMemoryRequirements(3) Manual Page

## Name

vkGetDeviceBufferMemoryRequirements - Returns the memory requirements for specified Vulkan object

Loading… please wait.

## C Specification

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

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

    // Provided by VK_KHR_maintenance4
    // Equivalent to vkGetDeviceBufferMemoryRequirements
    void vkGetDeviceBufferMemoryRequirementsKHR(
        VkDevice                                    device,
        const VkDeviceBufferMemoryRequirements*     pInfo,
        VkMemoryRequirements2*                      pMemoryRequirements);

## Parameters

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

- `pInfo` is a pointer to a VkDeviceBufferMemoryRequirements 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-vkGetDeviceBufferMemoryRequirements-device-parameter
  `device` must be a valid VkDevice handle

- VUID-vkGetDeviceBufferMemoryRequirements-pInfo-parameter
  `pInfo` must be a valid pointer to a valid VkDeviceBufferMemoryRequirements structure

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