[ndnSIM] Question for Pending Interest Table

[Xee]

Hi Alex
Thanks for your email, I am trying to use the funcation to process the output with numbers as:

std::cout << (100)-(pit->GetSize ());

I want to process the value of PIT size from function and calculate with numbers using arithmetical operations. But when I use this function I am receiving the following errors:

Hi Xee,

What kind of error? pit->GetSize () returns just size_t value, which you should be able to use in any way.  Can post the actual error with a context (where are you calling from and how pit variable is defined).

Hi Alex

I am trying to make some mathematical operations with pit->GetSize () function output, 
but it is giving me error. Is there any way to process the output of this function ?

Hi Alex

Is is possible to set variable timeout for PIT entries during simulation ?
