A C function should never throw.

That's really ugly, though. Also, it will probably free it, not delete
it (ie. its destructor won't be called).
+void freeifaddrs(struct ifaddrs *ifa)
void
freeifaddrs(struct ifaddrs* ifa)
Finally, since it's part of libbnetapi.so, why don't you put its
function prototype in a standard header (and since it's also part of glibc).
Bye,
Axel.
