ALARM(3)							      ALARM(3)

NAME
       alarm - schedule signal after specified time

SYNOPSIS
       unsigned int alarm(unsigned seconds);

DESCRIPTION
       This interface is made obsolete by setitimer(2).

       Alarm  causes signal SIGALRM, see sigvec(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 longest specifiable delay time
       is 2147483647 seconds.

       The  return  value  is  the  amount of time previously remaining in the
       alarm clock.
