Hmm, I did try to fopen in binary mode. It looks like when I call pcap_fopen_offline() that it is defined as pcap_hopen_offline(), if that is the trick you are speaking of. Later, I get the pointer from pcap_file() however the underlying sf.rfile pointer is different between the dll and the exe. I will have to double check the example.
I did find somewhat of a solution. I can call pcap_dump_ftell() to find the position in the file on the dll side, then open the file up on the exe side without using pcap and manually read the headers and data in the file. I feel though that this is not the best way. Is there something like a pcap_dump_fseek() that would let me go to the beginning of the packet on the pcap side. If so that would be exactly what I need.
