| To determine whether a queue family of a physical device supports |
| presentation to an X11 server, using the Xlib client-side library, call: |
| |
| include::{generated}/api/protos/vkGetPhysicalDeviceXlibPresentationSupportKHR.txt[] |
| |
| * pname:physicalDevice is the physical device. |
| * pname:queueFamilyIndex is the queue family index. |
| * pname:dpy is a pointer to an Xlib code:Display connection to the server. |
| * pname:visualId is an X11 visual (code:VisualID). |
| |
| This platform-specific function can: be called prior to creating a surface. |
