+ALARM(2)                  Minix Programmer's Manual                   ALARM(2)
+
+
+NAME
+     alarm - schedule signal after specified time
+
+SYNOPSIS
+     #include <unistd.h>
+
+     unsigned int alarm(unsigned int seconds)
+
+DESCRIPTION
+     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.
+

+     pause(2), sigsuspend(2), sigaction(2), sleep(3).
