Not really.

Yes. After you have called listen, you can call the 4-argument variant of
select on that socket. If the socket is ready for reading, a connection is
pending.

Just closing the socket should suffice.

Same as on other platforms

     If how is 0, then further receives will be disallowed.  If  how
     is  1,  then further sends will be disallowed.  If how is 2,
     then further sends and receives will be disallowed.
