ALARM(2)            Linux Programmer's Manual            ALARM(2)
+

+
+
NAME
+
       alarm - set an alarm clock for delivery of a signal
+
+
SYNOPSIS
+
       #include <unistd.h>
+
+       long alarm(long seconds);
+
+
DESCRIPTION
+
       alarm arranges for a SIGALRM signal to be delivered to the
+       process in seconds seconds.
+
+       If seconds is zero, no new alarm is scheduled.
+
+       In any event any previously set alarm is cancelled.
+
+
RETURN VALUE
+
       alarm returns the number of seconds  remaining  until  any
+       previously  scheduled  alarm  was  due to be delivered, or
+       zero if there was no previously scheduled alarm.
+
+
NOTES
+
       alarm and setitimer share the same  timer;  calls  to  one
+       will interfere with use of the other.
+
+       Scheduling delays can, as ever, cause the execution of the
+       process to be delayed by an arbitrary amount of time.
