Yes, for better or worse, swish-e.h contains just the functions exported
by the library, and also does not expose the internal layout of the
structures. I think it's a debatable point if using void * for the
"object" data types is a good thing.
You should not use both.

No. swish-e.h is really the API, but just the exported one. Why does the
"project" need to include the header? The C source files do that.
It's ugly and also a bit risky to have different headers (swish-e.h
contains functions declared in a bunch of different headers), but the
"library" was provided after the binary, so the design has a bit to be
desired. It would have been better to start with the API and then build
on that. Maybe someday things can be rearranged to make it a bit

That means the property name passed in the call does not exist in the

You are confusing MetaNames with PropertyNames.

Swish will abort if the .prop file cannot be found.

Sounds good. As long as it's generic enough for other's to use.

I don't know how it works on Windows, but the swish-e.h header file should
go into a standard location (by default it goes in /usr/local/include).
So I'd think you would say #include <swish-e.h> in your source code.
