BSD套接字兼容包装的Winsock吗？

Question

I'm attempting to port a Linux application to Windows. The application isn't too complex, using all fairly standard code, with few external dependencies. The main dependencies are libelf (which compiles fine under mingw), pthreads (there appears to be a win32 version available), and sockets. The main problem is with sockets...Windows provides WinSock, but this is not 100% compatible with BSD (Berkeley) sockets as used by all *nixes. What I'm wondering is, has anybody written a wrapper on windows that exposes a BSD socket API, but calls Winsock on the backend, to ease porting?

Answer 1

I would recommend using cygwin.dll . It's built for bringing over *nixes to windows including sockets, file IO, etc.

Answer 2

For the most part, you'll just have to make sure that WSAStartup() and WSACleanup() are called at start and end, otherwise, basic BSD sockets will translate pretty well. You could create some static global variable that gets checked for each call to the socket calls, and call WSAStartup() and WSACleanup() accordingly. As for poll() ... well, it translates quite easily to select().
