Free-threaded CPython builds (i.e. python3.13t and the 3.13t ABI) are not currently supported.
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.
