NAME
     shutdown - shut down part of a full-duplex connection

SYNOPSIS
     int shutdown(s, how)
     int s, how;

DESCRIPTION
     The shutdown call causes all or part of a full-duplex
     connection on the socket associated with s to be shut down.
     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.

STATUS MESSAGES AND VALUES
     A 0 is returned if the call succeeds, -1 if it fails.

     The call succeeds unless:

     EBADF
          s is not a valid descriptor.

     ENOTSOCK
          s is a file, not a socket.

     ENOTCONN
          The specified socket is not connected.
