ALARM(2)						     Linux Programmer's Manual							  ALARM(2)

NAME
alarm - set an alarm clock for delivery of a signal SYNOPSIS
#include <unistd.h> unsigned int alarm(unsigned int seconds); DESCRIPTION
alarm() arranges for a SIGALRM signal to be delivered to the calling process in seconds seconds. If seconds is zero, no new alarm() is scheduled. In any event any previously set alarm() is canceled. RETURN VALUE
alarm() returns the number of seconds remaining until any previously scheduled alarm was due to be delivered, or zero if there was no pre- viously scheduled alarm. CONFORMING TO
SVr4, POSIX.1-2001, 4.3BSD. NOTES
alarm() and setitimer(2) share the same timer; calls to one will interfere with use of the other. sleep(3) may be implemented using SIGALRM; mixing calls to alarm() and sleep(3) is a bad idea. Scheduling delays can, as ever, cause the execution of the process to be delayed by an arbitrary amount of time. SEE ALSO
