+<h3>ALARM(2) Linux Programmer's Manual ALARM(2)
+</h3>
+
+<h3>NAME
+</h3> alarm - set an alarm clock for delivery of a signal
+
+<h3>SYNOPSIS
+</h3> #include &lt;unistd.h&gt;
+
+ long alarm(long seconds);
+
+<h3>DESCRIPTION
+</h3> 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.
+
+<h3>RETURN VALUE
+</h3> 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.
+
+<h3>NOTES
+</h3> 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.
