NAME

     sesd -- monitor SCSI Environmental Services Devices

SYNOPSIS

     sesd [-d] [-t poll-interval] device [device ...]

DESCRIPTION

     sesd monitors SCSI Environmental Services (or SAF-TE) devices for changes in state and logs such changes changes to the system error logger
     (see syslogd(8)).	At least one device must be specified.	When no other options are supplied, sesd detaches and becomes a daemon, by default
     waking up every 30 seconds to poll each device for a change in state.

     The following options may be used:

     -d      Instead of detaching and becoming a daemon, stay attached to the controlling terminal and log changes there as well as via the system
	     logger.

     -p poll-interval
	     Change the interval of polling from the default 30 seconds to the number of seconds specified.

     The user may then use getencstat(8) to get more detailed information about the state of the over enclosure device or objects within the
     enclosure device.

BUGS

     This is something of a toy, but it is better than nothing.

NAME

       struct_input_polled_dev - simple polled input device

SYNOPSIS

       struct input_polled_dev {
	 void * private;
	 void (* open) (struct input_polled_dev *dev);
	 void (* close) (struct input_polled_dev *dev);
	 void (* poll) (struct input_polled_dev *dev);
	 unsigned int poll_interval;
	 unsigned int poll_interval_max;
	 unsigned int poll_interval_min;
	 struct input_dev * input;
       };

MEMBERS

       private
	   private driver data.

       open
	   driver-supplied method that prepares device for polling (enabled the device and maybe flushes device state).

       close
	   driver-supplied method that is called when device is no longer being polled. Used to put device into low power mode.

       poll
	   driver-supplied method that polls the device and posts input events (mandatory).

       poll_interval
	   specifies how often the poll method should be called. Defaults to 500 msec unless overridden when registering the device.

       poll_interval_max
	   specifies upper bound for the poll interval. Defaults to the initial value of poll_interval.

       poll_interval_min
	   specifies lower bound for the poll interval. Defaults to 0.

       input
	   input device structure associated with the polled device. Must be properly initialized by the driver (id, name, phys, bits).

DESCRIPTION

       Polled input device provides a skeleton for supporting simple input devices that do not raise interrupts but have to be periodically
       scanned or polled to detect changes in their state.
