Function wayland_raw_protocol_bindings::client::wayland::wl_subsurface::wl_subsurface_set_sync

pub unsafe fn wl_subsurface_set_sync(wl_subsurface: *mut wl_subsurface)

set sub-surface to synchronized mode

Change the commit behaviour of the sub-surface to synchronized mode, also described as the parent dependent mode.

In synchronized mode, wl_surface.commit on a sub-surface will accumulate the committed state in a cache, but the state will not be applied and hence will not change the compositor output. The cached state is applied to the sub-surface immediately after the parent surface's state is applied. This ensures atomic updates of the parent and all its synchronized sub-surfaces. Applying the cached state will invalidate the cache, so further parent surface commits do not (re-)apply old state.

See wl_subsurface for the recursive effect of this mode.
