Yes, it does.
And, yes, this does, I think, run the risk that you'll open the FILE * with one
version of the C runtime library and have WinPcap close it with another
version, which I am told
1) can happen
and
2) can cause crashes and other problems.
(I come from the UN*X world, where that sort of
mismatched-versions-of-the-C-library problem simply doesn't happen. You can
allocate stuff in a library and free it in the main program or another library,
and open a FILE * in the main program and close it in a library or open it in a
library and close it in the main program or another library, and all the
operations will be done by the same version of the C library.)
If this is causing problems, you might want to see whether you can use
pcap_hopen_offline() with a HANDLE instead.
