[ndnSIM] check content store entries periodically ?

Perhaps this would help a bit:

You basically create a callback function with the behavior you want  - you
pass the function pointer (similar to a delegate method, or closure in some
other languages) to the static Schedule method of the Simulator.

So, you'd create a method like this:

*handler(ofstream* outfile, int iteration) *
*   (*outfile)<<"Testing iteration "<<iteration<<std::endl;     *
*}//end handler*

Then, in your scenario, you schedule it to occur at a particular interval:

*Simulator::Schedule(Seconds(1), &handler, &outfile, i);*

This example is quite trivial, but you can make them arbitrarily complex.
I.e., you can, after the initial &handler, pass any of the necessary
parameters that your handler takes, to the Schedule method.

Also, this page might be useful (just search for Schedule) :
