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. 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. You need to link the DLL to your project.
