vkGetRandROutputDisplayEXT

When acquiring displays from an X11 server, an application may also wish to enumerate and identify them using a native handle rather than a VkDisplayKHR handle. To determine the VkDisplayKHR handle corresponding to an X11 RandR Output, call:

VkResult vkGetRandROutputDisplayEXT(
    VkPhysicalDevice physicalDevice,
    Display* dpy,
    RROutput rrOutput,
    VkDisplayKHR* pDisplay);

pub fn get_rand_r_output_display_ext(
    physical_device: vk::PhysicalDevice,
    dpy: *mut Display,
    rr_output: RROutput,
    p_display: *mut vk::DisplayKHR,
) -> vk::Result;

• physicalDevice is the physical device to query the display handle on.
• dpy is a connection to the X11 server from which rrOutput was queried.
• rrOutput is an X11 RandR output ID.
• pDisplay is a pointer to a VkDisplayKHR handle where the display is returned.

If there is no VkDisplayKHR corresponding to rrOutput on physicalDevice, VK_NULL_HANDLE will be returned in pDisplay.
