Regd ev_timer

[Varun Chandramohan]

Thanks Marc, that seem clear. Would you be able to answer the question I
asked Jann about the timer.

I have pasted my code in previous post that can be compiled directly. It
works now but if I just remove  ev_now_update(loop) from both my handlers
then the code goes bad and
I get timeout events even though the timer is stopped. Do you know why this
is happening? Even though my problem is solved I want to understand the
reason behind the issue.

Regards,
Varun
