C Specification

The VkBufferCreateInfo structure is defined as:

// Provided by VK_VERSION_1_0
typedef struct VkBufferCreateInfo {
    VkStructureType        sType;
    const void*            pNext;
    VkBufferCreateFlags    flags;
    VkDeviceSize           size;
    VkBufferUsageFlags     usage;
    VkSharingMode          sharingMode;
    uint32_t               queueFamilyIndexCount;
    const uint32_t*        pQueueFamilyIndices;
} VkBufferCreateInfo;

Members

  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • flags is a bitmask of VkBufferCreateFlagBits specifying additional parameters of the buffer.

  • size is the size in bytes of the buffer to be created.

  • usage is a bitmask of VkBufferUsageFlagBits specifying allowed usages of the buffer.

  • sharingMode is a VkSharingMode value specifying the sharing mode of the buffer when it will be accessed by multiple queue families.

  • queueFamilyIndexCount is the number of entries in the pQueueFamilyIndices array.

  • pQueueFamilyIndices is a list of queue families that will access this buffer (ignored if sharingMode is not VK_SHARING_MODE_CONCURRENT).

Description

Valid Usage
  • VUID-VkBufferCreateInfo-size-00912
    size must be greater than 0

  • VUID-VkBufferCreateInfo-sharingMode-00913
    If sharingMode is VK_SHARING_MODE_CONCURRENT, pQueueFamilyIndices must be a valid pointer to an array of queueFamilyIndexCount uint32_t values

  • VUID-VkBufferCreateInfo-sharingMode-00914
    If sharingMode is VK_SHARING_MODE_CONCURRENT, queueFamilyIndexCount must be greater than 1

  • VUID-VkBufferCreateInfo-sharingMode-01419
    If sharingMode is VK_SHARING_MODE_CONCURRENT, each element of pQueueFamilyIndices must be unique and must be less than pQueueFamilyPropertyCount returned by either vkGetPhysicalDeviceQueueFamilyProperties or vkGetPhysicalDeviceQueueFamilyProperties2 for the physicalDevice that was used to create device

  • VUID-VkBufferCreateInfo-flags-00915
    If the sparse bindings feature is not enabled, flags must not contain VK_BUFFER_CREATE_SPARSE_BINDING_BIT

  • VUID-VkBufferCreateInfo-flags-00916
    If the sparse buffer residency feature is not enabled, flags must not contain VK_BUFFER_CREATE_SPARSE_RESIDENCY_BIT

  • VUID-VkBufferCreateInfo-flags-00917
    If the sparse aliased residency feature is not enabled, flags must not contain VK_BUFFER_CREATE_SPARSE_ALIASED_BIT

  • VUID-VkBufferCreateInfo-flags-00918
    If flags contains VK_BUFFER_CREATE_SPARSE_RESIDENCY_BIT or VK_BUFFER_CREATE_SPARSE_ALIASED_BIT, it must also contain VK_BUFFER_CREATE_SPARSE_BINDING_BIT

  • VUID-VkBufferCreateInfo-pNext-00920
    If the pNext chain includes a VkExternalMemoryBufferCreateInfo structure, its handleTypes member must only contain bits that are also in VkExternalBufferProperties::externalMemoryProperties.compatibleHandleTypes, as returned by vkGetPhysicalDeviceExternalBufferProperties with pExternalBufferInfo->handleType equal to any one of the handle types specified in VkExternalMemoryBufferCreateInfo::handleTypes

  • VUID-VkBufferCreateInfo-flags-01887
    If the protected memory feature is not enabled, flags must not contain VK_BUFFER_CREATE_PROTECTED_BIT

  • VUID-VkBufferCreateInfo-None-01888
    If any of the bits VK_BUFFER_CREATE_SPARSE_BINDING_BIT, VK_BUFFER_CREATE_SPARSE_RESIDENCY_BIT, or VK_BUFFER_CREATE_SPARSE_ALIASED_BIT are set, VK_BUFFER_CREATE_PROTECTED_BIT must not also be set

  • VUID-VkBufferCreateInfo-pNext-01571
    If the pNext chain includes a VkDedicatedAllocationBufferCreateInfoNV structure, and the dedicatedAllocation member of the chained structure is VK_TRUE, then flags must not include VK_BUFFER_CREATE_SPARSE_BINDING_BIT, VK_BUFFER_CREATE_SPARSE_RESIDENCY_BIT, or VK_BUFFER_CREATE_SPARSE_ALIASED_BIT

  • VUID-VkBufferCreateInfo-deviceAddress-02604
    If VkBufferDeviceAddressCreateInfoEXT::deviceAddress is not zero, flags must include VK_BUFFER_CREATE_DEVICE_ADDRESS_CAPTURE_REPLAY_BIT

  • VUID-VkBufferCreateInfo-opaqueCaptureAddress-03337
    If VkBufferOpaqueCaptureAddressCreateInfo::opaqueCaptureAddress is not zero, flags must include VK_BUFFER_CREATE_DEVICE_ADDRESS_CAPTURE_REPLAY_BIT

  • VUID-VkBufferCreateInfo-flags-03338
    If flags includes VK_BUFFER_CREATE_DEVICE_ADDRESS_CAPTURE_REPLAY_BIT, the bufferDeviceAddressCaptureReplay or VkPhysicalDeviceBufferDeviceAddressFeaturesEXT::bufferDeviceAddressCaptureReplay feature must be enabled
