# VkBufferUsageFlags2CreateInfo(3) Manual Page

## Name

VkBufferUsageFlags2CreateInfo - Extended buffer usage flags

Loading… please wait.

## C Specification

The `VkBufferUsageFlags2CreateInfo` structure is defined as:

    // Provided by VK_VERSION_1_4
    typedef struct VkBufferUsageFlags2CreateInfo {
        VkStructureType        sType;
        const void*            pNext;
        VkBufferUsageFlags2    usage;
    } VkBufferUsageFlags2CreateInfo;

or the equivalent

    // Provided by VK_KHR_maintenance5
    typedef VkBufferUsageFlags2CreateInfo VkBufferUsageFlags2CreateInfoKHR;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `usage` is a bitmask of VkBufferUsageFlagBits2 specifying allowed usages of the buffer.

## Description

If this structure is included in the `pNext` chain of a buffer creation structure, `usage` is used instead of the corresponding `usage` value passed in that creation structure, allowing additional usage flags to be specified. If this structure is included in the `pNext` chain of a buffer query structure, the usage flags of the buffer are returned in `usage` of this structure, and the usage flags representable in `usage` of the buffer query structure are also returned in that field.

Valid Usage (Implicit)

- VUID-VkBufferUsageFlags2CreateInfo-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_BUFFER_USAGE_FLAGS_2_CREATE_INFO`

- VUID-VkBufferUsageFlags2CreateInfo-usage-parameter
  `usage` must be a valid combination of VkBufferUsageFlagBits2 values

- VUID-VkBufferUsageFlags2CreateInfo-usage-requiredbitmask
  `usage` must not be `0`
