C++ (Cpp) gs_shutdown_port Examples

Example #1

void gs_hangup(struct tty_struct *tty)
{
	struct gs_port   *port;

	func_enter ();

	if (!tty) return;

	port = tty->driver_data;
	tty = port->tty;
	if (!tty) 
		return;

	gs_shutdown_port (port);
	port->flags &= ~(ASYNC_NORMAL_ACTIVE|GS_ACTIVE);
	port->tty = NULL;
	port->count = 0;

	wake_up_interruptible(&port->open_wait);
	func_exit ();
}
