ALARM(2)        DOMAIN/IX Reference Manual (SYS5)        ALARM(2)



NAME
     alarm - set a process alarm clock

USAGE
     unsigned alarm (sec)
     unsigned sec;

DESCRIPTION
     Alarm instructs the alarm clock of the calling process to
     send the signal SIGALRM to the calling process, after the
     number of real-time seconds specified by sec have elapsed.
     See signal(2) for a discussion of signals.

     Alarm requests are not stacked; successive calls by alarm
     reset the alarm clock of the calling process.

     If sec is zero, any pending alarm request is cancelled.

RETURN VALUE
     Alarm returns the amount of time left in the alarm clock
     from the previous call.
