Getting header of received UDP packet

[Philliam Auriemma]

Hello,
I am programming an application which will send and receive UDP
packets, however for the received packets I need to be able to read
the header information. Is this possible in Winsock? As far as I am
aware, it strips the header information and just gives you the data of
the packet. If not, would something else do it like WinPCap or
something else?

You'll have to ask on a platform specific group, this is out of scope
for the C++ language. Or google for raw sockets.

This is out of scope of C++. consult Steven's on unix socket for more
theoretical information have a look at TCP/IP by Komer.

This is out of scope of C++.

To be a little pedantic, just in case any reader gets the wrong idea,
it's not "out of scope of C++," but rather "off topic in comp.lang.c++."
