## Name

VkNativeBufferUsageOHOS - The usage list of the OH_NativeBuffer object

Loading… please wait.

## C Specification

To obtain optimal Open Harmony OS native buffer usage flags for specific image creation parameters, add a `VkNativeBufferUsageOHOS` structure to the `pNext` chain of a VkImageFormatProperties2 structure passed to vkGetPhysicalDeviceImageFormatProperties2.

The `VkNativeBufferUsageOHOS` structure is defined as:

    // Provided by VK_OHOS_external_memory
    typedef struct VkNativeBufferUsageOHOS {
        VkStructureType    sType;
        void*              pNext;
        uint64_t           OHOSNativeBufferUsage;
    } VkNativeBufferUsageOHOS;

## Members

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

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

- `OHOSNativeBufferUsage` returns the Open Harmony OS buffer usage flags.

## Description

Valid Usage (Implicit)

- VUID-VkNativeBufferUsageOHOS-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_NATIVE_BUFFER_USAGE_OHOS

Structure Chaining

Extends the structure

  - VkImageFormatProperties2
