Hi all,
For a rather strange application, I need async I/O support from the
packet32.dll module. What I *really* need is select()-like behavior
on a bunch of open interfaces, but I can easily simulate that as long
as I have async (overlapped) I/O on the interface handles.
While implementing the code in my application, and hitting some
errors from the Packet32 DLL, I checked the source of Packet32. It
looks like the channel to the kernel driver is opened using the
standard
AdapterObject->hFile = CreateFile( ... )
calling sequence, which is as expected. I can simply bypass the
standard PacketReceivePacket() call and replace it with my own code
to handle the overlapped-ness, no problem there.
What *is* sadly not working, is the actual parameters to the CreateFile
call above... the adapter handle is *not* opened with the
FILE_FLAG_OVERLAPPED parameter enabled, so, overlapped I/O will not
work on these handles.
Although I am currently still using V2.3 on my development system, it
looks (from the source) that V3.0 does not have it, either.
Since I don't have the Microsoft SDK/DDK installed (just Vissual Studio
V6.0SP5+PP), I cannot compile the "changed" packet32.c myself :(
Question: could one of the developers of the package help me out?
Thanks,
Fred
