The equivalent CFFI code would be something like:
(with-foreign-object (p :pointer) (getifaddrs p) (foreign-slot-value (mem-ref p :pointer) 'ifaddrs 'name))
If you define NAME's type to be :STRING, that code will yield a Lisp string.
That works, thanks
The man page shows that the allocated struct should be free calling freeifaddrs:
void freeifaddrs(struct ifaddrs *ifa);
(freeifaddrs (cffi:mem-ref p :pointer))
is that the correct way to call freeifaddrs?
