HI all,
i am working on a project , where i came across a situation where i need
to execute a function when a timer expires ,exactly similar to functionality of the
timeout() kernel function but i need this in userland(application), and the execution
of the function is time sensitive, it should be run immediately when timer expires.
i can't be using poll or select for timer becuse those will block the process untill
the timer expires.for me the proess should not be blocked.
and i also thought of taking the service of the timeout function by writing a system
call and using signaling mechanism but i think this will become expensive when the
number of timers to be checked increeses.
i read the kern_timeout.c code that is very good implentation.with very less expensive.
but i think user unable to enjoy that service.
i will thankful if somebody can tell if there is any such a service or way provided
by os( that i overlooked).
thanks,
-Pradeep
