<DIV><FONT size=2>The user level part of WinPcap (wpcap.dll and packet.dll, plus
a couple other minor binaries) are 32-bit only. We do not provide 64-bit user
level libraries because up to now there was not much request for
that.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Wrt how WinPcap works on 64bit, this is the explanation. The
kernel driver (npf.sys) is 64bit. This is a requirement (kernel drivers must be
64bit on a 64bit Windows OS). The user level part is 32bit, i.e. a
WinPcap-based application is always a 32-bit application. On 64bit Windows, it
runs on WoW64 (Windows on Windows64) i.e. it runs in a 32bit environment, and
the OS provides the necessary thunking to have the 32bit application to
communicate with the 64bit kernel and 64bit kernel driver.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Providing 64bit versions of the WinPcap user level libraries
is definitely in our todo list, but at the moment it's a low priority task due
to the very few requests we had for this feature.</FONT></DIV>

to wpcap.lib</DIV>
<DIV><BR></DIV>
<DIV>I need help in compiling my program.</DIV>
<DIV>i installed winpcap driver + dll (the exe file) on 64 bit machine.</DIV>
<DIV>i wrote a program that using pcap functions. when i am compling it
in 64 bit mode i get an unsloved link symbol to the pcap functions,
but when i am compling it in 32 bit mode, everything is working fine. i think
the wpcap.lib from the developer pack is for 32 bit, but i can't understand
why it is working on 64 bit machine? - didn't the installation of winpcap
install a dll of 64 bit?</DIV>
<DIV>please help..</DIV>
<DIV> </DIV>
