This loop was written in a buggy style, causing a NULL driver ptr to be passed to copyScreen(). copyScreen() only uses that to generate an identifier string, so this is mostly harmless on systems that accept NULL for asprintf() "%s" format. (the generated identifiers are off by one wrt the driver names and the last one contains NULL. For systems that don't accept NULL for '%s' this would cause a segmentation fault when this code is used (no xorg.conf, but partial config in xorg.conf.d for instance).

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
