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.
