How to deal with NIC frames in c++

Question

I'm thinking about writing a program as my junior project ... the program should connect to different networks on the same system i.e if the PC has 2 NIC each one with different type (e.g.Ethernet and WIFI ) the program should read the frame from an NIC , changes the header so it matches the other NIC header's type , and then send it to the proper NIC ..

so can anyone direct me what to look for ,and what to read about in order to get this project done ??

the platform isn't that important to me , im ready to do it or linux or windows and the language is not a big deal also because im taking this project to learn as much as i can but as the title says , it would be much better to have it in c++

thanks in advance

The libpcap library would get you at least half of what you are looking for.
