Well, guess I spoke too soon about libffi! The documentation is pretty
sketchy, but I dug around in the source of the CVS version of libffi
and found how to do callbacks. So after some hours of late night
hacking I ripped out ffcall and put libffi in its place. The Alien API
remains the same, so I am calling this version 0.3.1.
I uploaded a new rockspec and removed the rockspec for 0.3 from the
repository. All traces of ffcall are gone from the distribution. I
incorporated the libffi source code in the distribution because the
version in MacPorts is buggy.
Enjoy the GPL-free Alien 0.3.1!
I've decided to try using Alien as a unit testing platform for a C
library I wrote. While working on this I found a few deficiencies......
* callbacks cannot be nil - relatively easy to patch... in
alien_check_callback, check for nil and return NULL if so... [I think
thats right...]
* callbacks cannot be passed into a callback...
EX: I have a callback that receives a 'next' callback that is to be
called with results (and can be called multiple times, so return value
cannot be hacked in well.)
API suggestion: anonymous callbacks should be able to accept the
:types function to apply types and make them callable.
