Ok, in the documentation of winpcap I found the function pcap_dump_open().
It opens a file for another function ...loop() with captures packet and saves it in this file.
But I have to open the file and have to write my data in this file.. not captureing it with this loop() function. It is possible to insert my data into a struct and then save this structure into a .pcap file?
I need the "low-level" description of this file format. It should be possible to implement an own easy function to save the data.

You are looking for libpcap (or WinPcap on Windows). Works like a charm,
and has lots of language bindings (I've used it with Ruby).
