those warnings (e.g. ioctl) with::

``nitpick_ignore`` [1].

With this change all the ".. cpp:function:: int ioctl(..)" descriptions

ioctl(..)", without getting any warnings. E.g.::

  .. c:function:: int ioctl( int fd, int request, struct cec_event *argp )

The main effect, is that we get those *CPP-types* back into Sphinx's C-
