The struct swsopts is passed to sws_init(), which can set "globals" in
the "library" (as the sample implementation does).

The example provided then makes use of the __sws_debug variable to
identify whether or not it's running in debug mode or not.

So unless I messed up the example (which is of course entirely
possible), you should be able to pass information via sws_init
