NAME
     alarm - set a process alarm clock

SYNOPSIS
     #include <unistd.h>

     unsigned alarm(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)].

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

     If sec is 0, any previously made alarm request is canceled.

     fork sets the alarm clock of a new process to 0 [see fork(2)].  A process
     created by the exec family of routines inherits the time left on the old
     process's alarm clock.

SEE ALSO
     fork(2), exec(2), pause(2), signal(2), sigset(2).

DIAGNOSTICS
     alarm returns the amount of time previously remaining in the alarm clock
     of the calling process.

BUGS
     alarm calls reset the itimer clock of the calling process.
