I am using winsock.h in a C++ program. I am getting two function errors that can not be resolved. What is wrong?

Question

I am programming using winsock. In my program there are two functions, inet_ntop and getaddressinfo. The compile is saying they can not be resolved. What am I missing from my program?

Answer 1

Windows provides a different function for that first operation: InetNtop. The arguments are the same, so you should be able to:



#define inet_ntop InetNtop



...to solve that one.



getaddressinfo should be getaddrinfo, even for Berkely sockets.

Answer 2

"cannot be resolved" is usually a linker error. Are you including the library (dll) which contains these functions in your build?

Answer 3

Hmmm.
