# vkCreateBuffer(3) Manual Page

## Name

vkCreateBuffer - Create a new buffer object

Loading… please wait.

## C Specification

To create buffers, call:

    // Provided by VK_VERSION_1_0
    VkResult vkCreateBuffer(
        VkDevice                                    device,
        const VkBufferCreateInfo*                   pCreateInfo,
        const VkAllocationCallbacks*                pAllocator,
        VkBuffer*                                   pBuffer);

## Parameters

- `device` is the logical device that creates the buffer object.

- `pCreateInfo` is a pointer to a VkBufferCreateInfo structure containing parameters affecting creation of the buffer.

- `pAllocator` controls host memory allocation as described in the Memory Allocation chapter.

- `pBuffer` is a pointer to a VkBuffer handle in which the resulting buffer object is returned.

## Description

Valid Usage

- VUID-vkCreateBuffer-device-09664
  `device` must support at least one queue family with one of the `VK_QUEUE_VIDEO_ENCODE_BIT_KHR`, `VK_QUEUE_VIDEO_DECODE_BIT_KHR`, `VK_QUEUE_SPARSE_BINDING_BIT`, `VK_QUEUE_TRANSFER_BIT`, `VK_QUEUE_COMPUTE_BIT`, or `VK_QUEUE_GRAPHICS_BIT` capabilities

- VUID-vkCreateBuffer-flags-00911
  If the `flags` member of `pCreateInfo` includes `VK_BUFFER_CREATE_SPARSE_BINDING_BIT`, and the `extendedSparseAddressSpace` feature is not enabled, creating this `VkBuffer` must not cause the total required sparse memory for all currently valid sparse resources on the device to exceed `VkPhysicalDeviceLimits`::`sparseAddressSpaceSize`

- VUID-vkCreateBuffer-flags-09383
  If the `flags` member of `pCreateInfo` includes `VK_BUFFER_CREATE_SPARSE_BINDING_BIT`, the `extendedSparseAddressSpace` feature is enabled, and the `usage` member of `pCreateInfo` contains bits not in `VkPhysicalDeviceExtendedSparseAddressSpacePropertiesNV`::`extendedSparseBufferUsageFlags`, creating this `VkBuffer` must not cause the total required sparse memory for all currently valid sparse resources on the device, excluding `VkBuffer` created with `usage` member of `pCreateInfo` containing bits in `VkPhysicalDeviceExtendedSparseAddressSpacePropertiesNV`::`extendedSparseBufferUsageFlags` and `VkImage` created with `usage` member of `pCreateInfo` containing bits in `VkPhysicalDeviceExtendedSparseAddressSpacePropertiesNV`::`extendedSparseImageUsageFlags`, to exceed `VkPhysicalDeviceLimits`::`sparseAddressSpaceSize`

- VUID-vkCreateBuffer-flags-09384
  If the `flags` member of `pCreateInfo` includes `VK_BUFFER_CREATE_SPARSE_BINDING_BIT` and the `extendedSparseAddressSpace` feature is enabled, creating this `VkBuffer` must not cause the total required sparse memory for all currently valid sparse resources on the device to exceed `VkPhysicalDeviceExtendedSparseAddressSpacePropertiesNV`::`extendedSparseAddressSpaceSize`

- VUID-vkCreateBuffer-pNext-06387
  If using the VkBuffer for an import operation from a VkBufferCollectionFUCHSIA where a VkBufferCollectionBufferCreateInfoFUCHSIA has been chained to `pNext`, `pCreateInfo` must match the VkBufferConstraintsInfoFUCHSIA::`createInfo` used when setting the constraints on the buffer collection with vkSetBufferCollectionBufferConstraintsFUCHSIA

Valid Usage (Implicit)

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

- VUID-vkCreateBuffer-pCreateInfo-parameter
  `pCreateInfo` must be a valid pointer to a valid VkBufferCreateInfo structure

- VUID-vkCreateBuffer-pAllocator-parameter
  If `pAllocator` is not `NULL`, `pAllocator` must be a valid pointer to a valid VkAllocationCallbacks structure

- VUID-vkCreateBuffer-pBuffer-parameter
  `pBuffer` must be a valid pointer to a VkBuffer handle

Return Codes

On success, this command returns

  - `VK_SUCCESS`

On failure, this command returns

  - `VK_ERROR_OUT_OF_HOST_MEMORY`

  - `VK_ERROR_OUT_OF_DEVICE_MEMORY`

  - `VK_ERROR_INVALID_OPAQUE_CAPTURE_ADDRESS_KHR`
