## Name

VkNativeBufferPropertiesOHOS - Properties of external memory Open Harmony OS native buffer

Loading… please wait.

## C Specification

The `VkNativeBufferPropertiesOHOS` structure is defined as:

    // Provided by VK_OHOS_external_memory
    typedef struct VkNativeBufferPropertiesOHOS {
        VkStructureType    sType;
        void*              pNext;
        VkDeviceSize       allocationSize;
        uint32_t           memoryTypeBits;
    } VkNativeBufferPropertiesOHOS;

## Members

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

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

- `allocationSize` is the size of the external memory.

- `memoryTypeBits` is a bitmask containing one bit set for every memory type which the specified Open Harmony OS native buffer can be imported as.

## Description

Valid Usage (Implicit)

- VUID-VkNativeBufferPropertiesOHOS-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_NATIVE_BUFFER_PROPERTIES_OHOS`

- VUID-VkNativeBufferPropertiesOHOS-pNext-pNext
  `pNext` must be `NULL` or a pointer to a valid instance of VkNativeBufferFormatPropertiesOHOS

- VUID-VkNativeBufferPropertiesOHOS-sType-unique
  The `sType` value of each structure in the `pNext` chain must be unique
