I need to include this Ws2tcpip.h header file to my project. How can I do this? It's all because I need inet_ntop function from this header file.

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.


It doesn't work. "Reference to an unresolved external symbol _inet_ntop". I guess I can add my utils.c to my .d project when I compile project and I need write in this file function wrapper of inet_ntop.
