That's great!

It should have the same semantics as the path argument in voikkoInit. 
can indeed put anything there and still get the dictionaries that exist 
standard search locations. But in case you put a path to some directory 
that actually contains some extra dictionaries those should be listed in
addition to the ones in standard locations. If that does not work, it is
a bug. For example if you have some local dictionary under


and you provide "/opt/extra-dictionaries" as the path argument your
fi-x-something dictionary should be listed there.

Yes, that is the way to do it. The only reason why our C API has all 
functions is that the consumers of the library do not need to know how
to interpret the C (or C++) struct behind the dictionaries. It is hard
to get that right across all the platforms and compilers. The current 
makes it safe to use for example GCC compiled library on Windows from
application compiled with Visual Studio.
