Filtering paquets with pcap.h

Hello everybody!!

I am currently doing my intership and I need some tips for Pcap.h.

I search some tips tp filter my paquets in a C program with the Pcap.h librairy. The onlys thing I have found is thaht I can filter low level protocol with their name like (tcp/udp..). But for the higher protocols I have to use lower protocol names with ports number. Do you know I could do to filter the higher protocols with their name like (HTTP, MSNP...)

Thanks for you help.
