                      5: .nf
                      6: .B alarm(seconds)

                     11: This interface is obsoleted by setitimer(2).

                     14: .I Alarm
                     15: causes signal SIGALRM, see
                     16: .IR signal (3C),
                     17: to be sent to the invoking process
                     18: in a number of seconds given by the argument.
                     19: Unless caught or ignored, the signal terminates the process.
                     20: .PP
                     21: Alarm requests are not stacked; successive calls reset the alarm clock.

                     23: Because of scheduling delays,
                     24: resumption of execution of when the signal is
                     25: caught may be delayed an arbitrary amount.
                     26: The longest specifiable delay time is 2147483647 seconds.
                     27: .PP
                     28: The return value is the amount of time previously remaining in the alarm clock.
                     29: .SH "SEE ALSO"
