If that's the only function you need, you can just copy the declaration
of inet_ntop into your .d file and mark it as extern(C). E.g., on my OS
it's declared as:

	const char *inet_ntop(int af, const void *restrict src, char *restrict dst, socklen_t size);

Convert it to D:

	extern(C) const(char)* inet_ntop(int af, const(void)* src, char* dst, socklen_t size);

You probably also need:

	alias socklen_t = ...;

The definition can be found in your system header files. Probably you
can just get away with size_t.
