A former student of mine who's now doing computing degree is kind of
stuck doing C# all the time, but wants to use Csound as he did with
C/C++ when he did his final year with us. I guess that SWIG can be
used to create a C# interface, but is it hard to do? And does anyone
know if it is actually necessary?

Rory.

SWIG is not necessary. You can call the Csound "C" API using pinvoke.

Mike

Is that what an "FFI" is?

Almost, but not quite.

FFI stands for "Foreign Function Interface" and enables the caller's
program to impersonate C types, build a C calling convention stack
frame, and call a C calling convention function in a shared library.

pinvoke enables .NET programs to call C calling convention functions
that have types that can be impersonated in .NET.

pinvoke is a sort of subset of FFI.

What Anthony is talking about is probably pinvoke. As I said before it
should work fine with most Csound "C" API function calls.

Mike

I guess the Python module "ctypes" is more along the lines of an FFI
then. So if languages have FFIs and .NET has p/invoke, then why do we
need SWIG?

We recently added C# bindings to libpd, and it was remarkably easy,
even the callbacks from Pd to C#:
https://github.com/libpd/libpd/commit/f719d3d74e0b0010a27aac01c2304c43683f0436

I figure the same approach would work for Csound as well.
Cheers,

You don't need it but it's nice. With FFI you have write stuff by
hand. SWIG does it for you (mostly). Also its quite hard, impractical
really, to use FFI with C++ libraries, but SWIG is just for that.

Mike
