void restore_connect ( void )

Opens a separate connection to X11 for placeholder windows when restoring layouts.

This is done as a safety measure (users can xkill a placeholder window without killing their window manager) and for better isolation, both on the wire to X11 and thus also in the code.

bool restore_kill_placeholder ( xcb_window_t placeholder )

Kill the placeholder window, if placeholder refers to a placeholder window.

This function is called when manage.c puts a window into an existing container. In order not to leak resources, we need to destroy the window and all associated X11 objects (pixmap/gc).

void restore_open_placeholder_windows ( Con * con )

Open placeholder windows for all children of parent.

The placeholder window will vanish as soon as a real window is swallowed by the container. Until then, it exposes the criteria that must be fulfilled for a window to be swallowed by this container.
