alarm - execute a subroutine after a specified time
integer function alarm (time, proc)
This routine arranges for subroutine proc to be called after time seconds. If time is ``0'', the alarm is turned off and no routine will be
called. The returned value will be the time remaining on the last alarm.
SEE ALSO alarm(3C), sleep(3F), signal(3F)BUGS
Alarm and sleep interact. If sleep is called after alarm, the alarm process will never be called. SIGALRM will occur at the lesser of the
remaining alarm time or the sleep time.

alarm - set an alarm clock for delivery of a signal
unsigned int alarm(unsigned int seconds);
alarm() arranges for a SIGALRM signal to be delivered to the calling process in seconds seconds.
If seconds is zero, no new alarm() is scheduled.
In any event any previously set alarm() is canceled.
alarm() returns the number of seconds remaining until any previously scheduled alarm was due to be delivered, or zero if there was no pre-
viously scheduled alarm.
SVr4, POSIX.1-2001, 4.3BSD.
alarm() and setitimer(2) share the same timer; calls to one will interfere with use of the other.
sleep(3) may be implemented using SIGALRM; mixing calls to alarm() and sleep(3) is a bad idea.
Scheduling delays can, as ever, cause the execution of the process to be delayed by an arbitrary amount of time.

I'm kind of new to autosys, but I'm assuming there is a way to have Alarms be emailed instead of having to run jobscape and click the Alarm button to see what jobs have failed? Does anyone have an insight onto how this can be done? Thanks. (14 Replies)
