# vkGetScreenBufferPropertiesQNX(3) Manual Page

## Name

vkGetScreenBufferPropertiesQNX - Get Properties of External Memory QNX Screen Buffers

## C Specification

To determine the memory parameters to use when importing a QNX Screen buffer, call:

    // Provided by VK_QNX_external_memory_screen_buffer
    VkResult vkGetScreenBufferPropertiesQNX(
        VkDevice                                    device,
        const struct _screen_buffer*                buffer,
        VkScreenBufferPropertiesQNX*                pProperties);

## Parameters

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

- `buffer` is the QNX Screen buffer which will be imported.

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

## Description

Valid Usage
