(see the Setup parameters in MANUAL).
The command given in the '-s' option will be called with five parameters.
The first one is the time (in UTC) of the next timer event (as a time_t
type number), and the second one is the number of seconds from the current
time until the next timer event. Your program can choose which one to use
for programming some sort of hardware device that makes sure the computer
will be restarted in time before the next timer event. Your program must
also initiate the actual shutdown procedure of the computer. After this
your program should return to VDR. VDR will not automatically exit after
calling the shutdown program, but will rather continue normally until it
receives a SIGTERM when the computer is actually shut down. So in case
the shutdown fails, or the shutdown program for some reason decides not to
perform a shutdown, VDR will stay up and running and will call the shutdown
program again after another five minutes.
If there are currently no timers active, both parameters will be '0'.
In that case the program shall not set the hardware for automatic restart
and only perform the system shutdown. A program that uses the second parameter
to set the hardware for restart must therefore also check whether the first
parameter is '0'.

shutdown program for some reason decides not to perform a shutdown, VDR
will stay up and running and will call the shutdown program again after a
while. The command will be started in a separate background session, so it
can continue to run even after VDR has terminated.
The third parameter contains the number of the channel that will be recorded
by the next timer (or 0 if no timer is present), and the fourth parameter
contains the file name of the recording as defined in the timer (or an empty
string if no timer is present). These can be used by the shutdown program to
show that information on some display interface etc.
If there are currently no timers active and there is no plugin wakeup
time, both parameters will be '0'. In that case the program shall not set

A program that uses the second parameter to set the hardware for restart

If the wakeup time is given by a timer, the third parameter will be the
number of the channel that will be recorded, otherwise it will be 0. The
fourth parameter contains the file name of the recording as defined in the
timer, the name of the plugin that requested the wakeup time, or an empty
string if no wakeup time is present. These can be used by the shutdown
program to show that information on some display interface etc.
The fifth parameter indicates the reason why the shutdown was requested.
'0' means this is an automatic shutdown due to some timeout, while '1' means

periodic activity at a certain time at night, and if VDR shall wake up from
shutdown at that time, the plugin can implement the function
<p><table><tr><td bgcolor=#F0F0F0><pre>
