 * @param source      the source address we are connecting from.
 * @param destination the destination address we are connecting to.
 * @param data        the data to copy to the kernel-side socket buffer.
 * @param tcpFastOpen if {@code true}, set the flags needed to enable TCP FastOpen connecting.
 * @return The number of bytes copied to the kernel-side socket buffer, or the number of bytes sent to the
 * destination. This number is <em>negative</em> if connecting is left in an in-progress state,
 * or <em>positive</em> if the connection was immediately established.
 * @throws IOException if an IO error occurs, if the {@code data} is too big to send in one go,
 * or if the system call is not supported on your platform.
