Hi folks,
I just read this in tutorial-ffi.md:
The `"abi"` attribute applies to a foreign module (it can not be
applied
to a single function within a module), and must be either `"cdecl"`
or `"stdcall"`. Other conventions may be defined in the future.
Why must it be applied to a module as a whole? I don't quite
understand why this limitation is there.
The main reason for this arrangement is that one platform, OS X, does
symbol resolution using a 'two-level namespace' that includes the name
of the library, so encoding that information in the structure of the
bindings is attractive.
I just realized that this didn't answer your question at all. There is
no particular reason for the limitation except that nobody has written
the code to support it.
