 - Constructor, linux and mac platforms only provide the first version, windows platform also provides the second version.
 - In the first version, the **parameter fd is a non-blocking socket**, and the parameter ev is an I/O event, which is one of co::ev_read or co::ev_write. Calling the wait() method will wait for the I/O event specified by ev on the socket. When wait() returns successfully, users need to call recv, send or other I/O functions to complete the I/O operation. **On windows, fd must be a TCP socket**(For UDP, it is difficult to simulate the behavior of epoll or kqueue with IOCP).
-- The second version is only applicable to windows. Unlike the first version, fd can be a UDP socket, but users must manually call WSARecvFrom, WSASendTo or other functions to post an overlapped I/O operation to IOCP, and then call the wait() method. When wait() returns successfully, it means that IOCP has completed the I/O operation. See details in source code of [co::IoEvent](https://github.com/idealvin/co/blob/master/include/co/co/io_event.h), and implementation of [co::accept, co::connect, co::recvfrom, co::sendto](https://github.com/idealvin/co/blob/master/src/co/sock_win.cc) on windows.
