Packet.dll is a dynamic link library that offers a set of low level functions
|
|
to:
|
|
<ul>
|
|
<li>install, start and stop the NPF device driver</li>
|
|
<li>Receive packets from the NPF driver</li>
|
|
<li>send packets to the NPF driver</li>
|
|
<li>obtain the list of the available network adapters</li>
|
|
<li>retrieve various information about an adapter, like the description and
|
|
the list of addresses and netmasks</li>
|
|
<li>query and set various low-level parameters of an adapter</li>
|
|
</ul>
|
|
<p> There are two versions of packet.dll: the first one runs under Windows 95/98/ME, the second
|
|
one is for Windows
|
|
NT/2000/XP.</p>
|
|
<p>Packet.dll was created to provide a layer to access the low level
|
|
functionalities of WinPcap in a system independent way. This library handles all
|
|
the system-dependent details (like managing the devices, interacting with the OS
|
|
to manage the adapters, looking for the information in the registry and so on),
|
|
and exports an API that is uniform across all Windows OSes. In this way,
|
|
applications or libraries based on it can run without being recompiled
|
|
under any Windows operating system. </p>
|
|
<p>However, not all of the packet.dll API is totally portable: some advanced features, like kernel-mode dump, are present only in the WinNTx version of WinPcap,
|
|
while packet.dll for Win9x does not provide them. On the other side, the NTx
|
|
version is a superset of the 9x one, in other words all the function present in
|
|
the Win9x version are present in WinNTx too.</p>
|
|
<p>The other important feature of this library is its ability to handle NPF driver.
|
|
Packet.dll transparently installs and starts the driver when an application
|
|
attempts to access an adapter. This avoids the manual installation of the driver
|
|
through the control panel.</p>
|
|
<h2>Important note, read carefully!</h2>
|
|
<p>The source code of Packet.dll is freely available and completely documented.
|
|
However, packet.dll should be considered an internal API, because its purpose
|
|
inside WinPcap is to be a building block for the real public API: wpcap.dll.</p>
|
|
<p>As a consequence, since the <b>normal</b> and <b>suggested</b> way for an
|
|
application to use WinPcap is through wpcap.dll, <b>we don't guarantee that the packet.dll
|
|
API will not be changed in future releases of winpcap, and we don't provide
|
|
support for this API</b>. For the same reason, <b>this manual doesn't contain
|
|
any more the Doxygen-generated documentation of Packet.dll</b>: the user will
|
|
have to run Doxygen on his own to create it, or read the comments in the source
|
|
code.</p>
