Recently I am preparing the FreshLib network part, when I realized that the Windows and Linux socket API are actually identical. The same functions, the same constant names and the same structures.

Is it some standard, or what? Did someone knows some details about this subject?

Maybe because both are rooted on Berkeley sockets?

However, I think when it comes to more advanced non-berkeley features, you won't find the APIs quite similar (specially names, where Winsock has a very distinctive prefix on most function names).

Yes, it seems this is the reason. Actually I don't want to include advanced features in FreshLib, because it can be not portable (or too hard to be emulated) to Linux or other, not so complex OS (Menuet or Kolibri for example).

So, I will use the same API with some small modifications.
