C Specification
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:
// Provided by VK_EXT_acquire_xlib_display
VkResult vkGetRandROutputDisplayEXT(
VkPhysicalDevice physicalDevice,
Display* dpy,
RROutput rrOutput,
VkDisplayKHR* pDisplay);
Parameters
-
physicalDevice
The physical device to query the display handle on. -
dpy
A connection to the X11 server from whichrrOutput
was queried. -
rrOutput
An X11 RandR output ID. -
pDisplay
The corresponding VkDisplayKHR handle will be returned here.
Description
If there is no VkDisplayKHR corresponding to rrOutput
on
physicalDevice
, VK_NULL_HANDLE must be returned in
pDisplay
.
