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

  • VUID-vkGetAndroidHardwareBufferPropertiesANDROID-buffer-01884
    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)

  • VUID-vkGetAndroidHardwareBufferPropertiesANDROID-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkGetAndroidHardwareBufferPropertiesANDROID-buffer-parameter
    buffer must be a valid pointer to a valid AHardwareBuffer value

  • VUID-vkGetAndroidHardwareBufferPropertiesANDROID-pProperties-parameter
    pProperties must be a valid pointer to a VkAndroidHardwareBufferPropertiesANDROID structure

Return Codes
On success, this command returns

  • VK_SUCCESS

On failure, this command returns

  • VK_ERROR_OUT_OF_HOST_MEMORY

  • VK_ERROR_INVALID_EXTERNAL_HANDLE_KHR
