## Name

vkGetNativeBufferPropertiesOHOS - Obtain the properties of an OH_NativeBuffer Object

Loading… please wait.

## C Specification

To determine the memory parameters to use when importing an Open Harmony OS native buffer:

    // Provided by VK_OHOS_external_memory
    VkResult vkGetNativeBufferPropertiesOHOS(
        VkDevice                                    device,
        const struct OH_NativeBuffer*               buffer,
        VkNativeBufferPropertiesOHOS*               pProperties);

## Parameters

- `device` is the logical device that will be importing `buffer`.

- `buffer` is the OH_NativeBuffer object specifies the buffer for which its properties are to be queried.

- `pProperties` is a pointer to a VkNativeBufferPropertiesOHOS structure in which the properties of `buffer` are returned.

## Description

Valid Usage (Implicit)

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

- VUID-vkGetNativeBufferPropertiesOHOS-buffer-parameter
  `buffer` must be a valid pointer to a valid OH_NativeBuffer value

- VUID-vkGetNativeBufferPropertiesOHOS-pProperties-parameter
  `pProperties` must be a valid pointer to a VkNativeBufferPropertiesOHOS structure

  - VK_SUCCESS

On failure, this command returns

  - VK_ERROR_INVALID_EXTERNAL_HANDLE_KHR

  - VK_ERROR_OUT_OF_DEVICE_MEMORY

  - VK_ERROR_UNKNOWN
