SYNOPSIS

       int shutdown(int socket, int how);

DESCRIPTION
       The shutdown() function disables subsequent send() and receive() operations on a socket, depending on the value of the how argument.

PARAMETERS
       how	 Specifies the type of shutdown.  The values are as follows:

		 SHUT_RD      Disables further receive operations.

		 SHUT_WR      Disables further send operations.

		 SHUT_RDWR    Disables further send and receive operations.

       socket	 Specifies the file descriptor of the socket.

RETURN VALUES
       Upon successful completion, shutdown() returns 0.  Otherwise, -1 is returned and errno is set to indicate the error.

ERRORS
       The shutdown() function will fail if:

       EBADF	   The socket argument is not a valid file descriptor.

       EINVAL	   The how argument is invalid.

       ENOTCONN    The socket is not connected.

       ENOTSOCK    The socket argument does not refer to a socket.
