Loading… please wait.

## C Specification

To determine the memory parameters to use when importing an Android hardware buffer, call:

    // Provided by VK_ANDROID_external_memory_android_hardware_buffer
    VkResult vkGetAndroidHardwareBufferPropertiesANDROID(
        VkDevice                                    device,
        const struct AHardwareBuffer*               buffer,
        VkAndroidHardwareBufferPropertiesANDROID*   pProperties);

## Parameters

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

- `buffer` is the Android hardware buffer which will be imported.

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

## Description

Valid Usage

- `buffer` must be a valid Android hardware buffer object with at least one of the `AHARDWAREBUFFER_USAGE_GPU_`* flags in its `AHardwareBuffer_Desc`::`usage`

Valid Usage (Implicit)

- `device` must be a valid VkDevice handle

- `buffer` must be a valid pointer to a valid `AHardwareBuffer` value

- `pProperties` must be a valid pointer to a VkAndroidHardwareBufferPropertiesANDROID structure
