## Name

vkGetMemoryNativeBufferOHOS - Obtain an OH_NativeBuffer object

Loading… please wait.

## C Specification

To obtain an OH_NativeBuffer object, call:

    // Provided by VK_OHOS_external_memory
    VkResult vkGetMemoryNativeBufferOHOS(
        VkDevice                                    device,
        const VkMemoryGetNativeBufferInfoOHOS*      pInfo,
        struct OH_NativeBuffer**                    pBuffer);

## Parameters

- `device` is a valid Vulkan device object.

- `pInfo` is a pointer pointing to a `VkMemoryGetNativeBufferInfoOHOS` structure.

- `pBuffer` is a pointer to an OH_NativeBuffer object.

## Description
