+ * This defines a (unix-like) universal networking layer
+ * that should function on both windows and unix. (C - interface)
+ *
+ * This is of course only a subset of the full interface.
+ * functions required are:
+ *
+ * int tounet_close(int fd);
+ * int tounet_socket(int domain, int type, int protocol);
+ * int tounet_bind(int  sockfd,  const  struct  sockaddr  *my_addr,  
+ * 				socklen_t addrlen);
+ * int tounet_fcntl(int fd, int cmd, long arg);
+ * int tounet_setsockopt(int s, int level,  int  optname,  
+ * 				const  void  *optval, socklen_t optlen);
+ * ssize_t tounet_recvfrom(int s, void *buf, size_t len, int flags,
+ *                              struct sockaddr *from, socklen_t *fromlen);
+ * ssize_t tounet_sendto(int s, const void *buf, size_t len, int flags, 
+ * 				const struct sockaddr *to, socklen_t tolen);
+ *
+ * There are some non-standard ones as well:
+ * int tounet_errno();  	for internal networking errors 
+ * int tounet_init();  		required for windows 
+ * int tounet_checkTTL();  	a check if we can modify the ttl
