v1.17
* In API mode, when you get a function from a C library by writing
fn = lib.myfunc, you get an object of a special type for performance
reasons, instead of a <cdata ‘C-function-type’>. Before version 1.17 you
could only call such objects. You could write ffi.addressof(lib, “myfunc”)
in order to get a real <cdata> object, based on the idea that in these cases
in C you’d usually write &myfunc instead of myfunc. In version 1.17, the
special object lib.myfunc can now be passed in many places where CFFI expects
a regular <cdata> object. For example, you can now pass it as a callback to a
C function call, or write it inside a C structure field of the correct
pointer-to-function type, or use ffi.cast() or ffi.typeof() on it.
