Overall Offset of Packet within File

[lovejotd]

Is there anyway when I processing files, to know the offset of the current packet within the larger pcap file? I am having a hard time figuring/finding it out, and it could be helpful for me. Thanks!

What's the os?
In Linux you could get the file object and use ftell on it

Ideally this would need to work in either windows or Linux. Do you have an example of what you mean? Or link to an example?

Use FILE *pcap_file(pcap_t *) to get file pointer, then long int ftell ( FILE * stream ); to get file position.
You will need to write your own interop.
