dns spoof

[cr4kb0y]

hello everyone!
I am stdudying the dns spoof,and i got a source code about dns
spoof,but it can't run normaly,
I don't know why.so I come here for help.
the problem is :
PacketInitPacket(lppackets,sendbuf,sizeof(eth)+sizeof(arp));//
if(PacketSendPacket(lpadapter,lppackets,TRUE)==FALSE)
{
printf("PacketSendPacket in arpspoof Error: %d
\n",GetLastError());
return -1;
}
it can't send packets out.
and the error number is 0.
Can anybody here give me some hints!

Unfortunately, in clc you're wrong since your question seems to be
about some functions concerning networking, using some third-party
and probably system-specific library but not about the language C
(which hasn't any built-in support for networking and you don't
seem to have any obvious problems with C in what you posted).
Some functions look a bit as if they are from the WinPcap library
while another seems to be Windows specific (GetLastError()), so
asking in a group dedicated to programming under Windows will
probably be the best choice. If you do so it may be of advantage
if you give a bit more information (which system you're on, what
libraries you use and perhaps a bit more of source code).
