17/* Remark:
18 * 1999/11/21 experimental rewrite using IBM's PMWSock only
19 * -> some structural differences remain! (hostent)
20 * 1999/12/01 experimental rewrite works (TELNET)
21 * -> open issue: WSASetLastError / WSAGetLastError
22 * call SetLastError / GetLastError according to docs
23 *
24 * 2000/22/03 Complete rewrite -> got rid of pmwsock
25 *
26 * identical structures:
27 * - sockaddr_in
28 * - WSADATA
