ALARM(2) System Calls Manual ALARM(2)NAME
alarm - schedule signal after specified time
unsigned int alarm(unsigned int seconds)
Alarm causes signal SIGALRM, see sigaction(2), to be sent to the invoking process in a number of seconds given by the argument. Unless
caught or ignored, the signal terminates the process.
Alarm requests are not stacked; successive calls reset the alarm clock. If the argument is 0, any alarm request is canceled. Because of
scheduling delays, resumption of execution of when the signal is caught may be delayed an arbitrary amount.
The return value is the amount of time previously remaining in the alarm clock.
SEE ALSO pause(2), sigsuspend(2), sigaction(2), sleep(3).

ALARM(2) Linux Programmer's Manual ALARM(2)NAME
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, any pending alarm is canceled.
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)
