PCAP -> PFRING

Hi I have a program that captures packets with the libpcap library by calling the pcap-functions, e.g.

pcap_next(...)

.
I would like to use PF_RING for the program and therefore I would have to adjust the calling functions to

pfring_open(...)
pfring_recv(...)

I'm pretty knew in network programming and I was hopping that you could help me out, is that everything I would have to do just change the pcap-calls to the pfring calls or are there other things to consider?
