Passing value of a parameters in one .cpp file to another .cpp file

[Adnan86]

Hello,

In Attached file there are four files (router.cpp, router.hpp, islip.cpp and islip.hpp) for same project.

In router.cpp, there is a parameter which is (id or _id), that indicate the id of a router, for example, router 0 or router 1.

Now, I need the value of this parameter in islip.cpp, but I don't know how to pass the value of this parameters to this code.

Could you please someone explain it to me in a simple way as I am not an expert in C++.

Many thanks,
Adnan

The question can't be answered without knowing how the islip code is called related to router functionality. Is it called in one of the router functions or outside. In the latter case, how can you know which router instance islip is referring to?

These files belong to BOOKSIM simulator ( https://github.com/booksim/booksim2). an islip kind of allocator which used inside of the router.
router files inside of ../src/routers/router.cpp
and
Islip file inside ../src/allocators/islip.cpp

In router any time we need to allocate switches/ports we kind of use islip.

_id is an internal variable of the Router object, i'd guess it's initialized when constructing a new xxxRouter class. You should be able to pass it to the respective slip function when it's called. But you really need to look into the code details. I'm unable to review the full project now.
