From f53c05d3c2c19c139c52e9bd621c2654dd3dac69 Mon Sep 17 00:00:00 2001 From: Pekka Paalanen Date: Fri, 14 May 2021 16:04:45 +0300 Subject: [PATCH] libweston-desktop: introduce weston_desktop_client_destroy() This new function is callable explicitly, unlike the old function that used to have the same name. This will be needed when tearing down what weston_desktop_xwayland_init() puts up. Since calling weston_desktop_client_destroy() for an external client (one that has a wl_resource for this) is a bug, add asserts to prevent it. This will only be needed for the internal client: XWM.
