(That might help the "whole packet dumped" test.) Somehow measuring how large the byte count in the capture file "write()" calls in FreeBSD and "WriteFile()" calls are? (FreeBSD is probably doing 8K writes, assuming it's writing to an 8K/1K file system; I don't know what block size the MSVC++ version of the standard I/O library uses, but it might well use bigger chunks than 8K.) > Can those OO MSDN lobotomies actually be good things? I'm not sure the parts of the OS that are actually involved are particularly object-oriented; I have the impression most of the COM, etc. stuff lives well up in userland on Windows.
