To me, the optimal solution would be to simply use libffi (you would
only need logic to translate the rtti for the parameter types to libffi
format, and it would automagically work for all platforms), but since
that's an external dependency I guess that's not acceptable.
Well, the technical aspect is one thing, but its license is another issue.
Violating it happens too
quick.
The libffi license is basically a BSD license, that's no problem at all:
https://github.com/atgreen/libffi/blob/master/LICENSE
I am not a proponent of third-party dependencies.
Then, there is a practical issue:
I doubt libffi knows the Delphi calling conventions and the
pascal calling convention where the callee clears the stack
(or was it vice versa)? Since that is our main target group,
I consider this a serious problem.
Thirdly, from looking at the use of this library, you
will have to implement some kind of layer in between
anyway that describes the function, so I do not really
see the gain.
