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);

• physicalDevice The physical device to query the display handle on.
• dpy A connection to the X11 server from which rrOutput was queried.
• rrOutput An X11 RandR output ID.
• pDisplay The corresponding VkDisplayKHR handle will be returned here.

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