Timer application in linux

Hello everyone,
It is good to be here.
I am a newbie to Linux.Can anyone help me in designing a timer application.
The timer has to start.And after certain time interval the program should call a function continuously.It should not be in sleep mode.During the course of that time interval the program should execute the rest of the functions or statements.

Plz help me in doing so...thanx in advance

prima::timer

pod::Prima::Timer(3)					User Contributed Perl Documentation				      pod::Prima::Timer(3)

NAME

       Prima::Timer - programmable periodical events

SYNOPSIS

	   my $timer = Prima::Timer-> create(
	       timeout => 1000, # milliseconds
	       onTick  => sub {
		  print "tick!
";
	       },
	   );

	   $timer-> start;

DESCRIPTION

       Prima::Timer arranges periodical notifications to be delivered in certain time intervals.  The notifications are triggered by the system,
       and are seen as "Tick" events. There can be many active Timer objects at one time, spawning events simultaneously.

USAGE

       Prima::Timer is a descendant of Prima::Component.  Objects of Prima::Timer class are created in standard fashion:

	 my $t = Prima::Timer-> create(
	    timeout => 1000,
	    onTick  => sub { print "tick
"; },
	 );
	 $t-> start;

       If no `owner` is given, $::application is assumed.

       Timer objects are created in inactive state; no events are spawned. To start spawning events, <start()> method must be explicitly called.
       Time interval value is assigned using the <::timeout> property in milliseconds.

       When the system generates timer event, no callback is called immediately, - an event is pushed into stack instead, to be delivered during
       next event loop.  Therefore, timeout value is not held accurately, and events may take longer time to pass. More accurate timing scheme, as
       well as timing with precision less than a millisecond, is not supported by the toolkit.

API

   Properties
       timeout MILLISECONDS
	   Manages time interval between "Tick" events.  In set-mode call, if the timer is in active state ( see "get_active()", the new timeout
	   value is applied immediately.

   Methods
       get_active
	   Returns a boolean flag, whether object is in active state or not. In the active state "Tick" events are spawned after "::timeout" time
	   intervals.

       get_handle
	   Returns a system-dependent handle of object

       start
	   Sets object in active state. If succeed, or if the object is already in active state, returns 1. If the system was unable to create a
	   system timer instance, 0 is returned.

       stop
	   Sets object in inactive state.

   Events
       Tick
	   A system generated event, spawned every "::timeout" milliseconds if object is in active state.
