SYNOPSIS

9       integer function alarm (time, proc)
10       integer time
11       external proc

DESCRIPTION

14       This  routine arranges for subroutine proc to be called after time sec‐
15       onds. If time is ``0'', the alarm is turned off and no routine will  be
16       called.   The  returned  value  will  be the time remaining on the last
17       alarm.

BUGS

26       Alarm and sleep interact. If sleep is called  after  alarm,  the  alarm
27       process  will  never be called. SIGALRM will occur at the lesser of the
28       remaining alarm time or the sleep time.
