[Winpcap-users] How can I get the IP address ofgatewaythroughWinPcap

[Steighton_Haley at McAfee.com]

What he is saying is that you acknowledge that what you are doing is not
a good way of doing it.
 
You could use the function GetAdaptersInfo which gives you information
about the adapter, all of it's IP address, and all of it's gateway
information.
 
Try that instead of this writing to a file kludge.

			thank you 
			but i used the windows command "ipconfig /all "
to obtaine the information of gateway
			then redirect the output to the file
			i get the info through reading this file
			although this is not a good way, i think that
this is a available one.

				Agreed. Also the ip of gateway can be
read from registry
	
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\I
nterfaces\{64B3C6C6-A3C4-4293-AC98-5BF7C17B467D}]\DefaultGateway 
				(DHCPDefaultGateway if dhcp enabled)
				{64B3C6C6-A3C4-4293-AC98-5BF7C17B467D}
can be get by parsing the
				device name of pcap_t. I was doing like
this because I don't want to
				download win platform sdk:-)
