       int shutdown(int s, int how);

DESCRIPTION

       The shutdown() call shuts down all or part of a full-duplex connection on the socket associated with s. If how is SHUT_RD, further receives
       are disallowed. If how is SHUT_WR, further sends are disallowed. If how is SHUT_RDWR, further sends and receives are disallowed.

       The how values should be defined constants.

       -1 is returned if the call fails.

ERRORS

       EBADF	   The s value is not a valid file descriptor.

       ENOMEM	   Insufficient user memory is available for the operation to complete.

       ENOSR	   Insufficient STREAMS resources are available for the operation to complete.

       ENOTCONN    The specified socket is not connected.

       ENOTSOCK    The s value is not a socket.
