Ok, I found half of the error. I write in C++, not C and the file was
accidentally saved as .c. (Note to self: No more coding at 2 am).
Anyways, there are still problems.
C:\Documents and Settings\root\My Documents\narayan\main.cpp(67) :

C:\Documents and Settings\root\My Documents\narayan\main.cpp(67) :

Line 67:

-1) // find network devices or error

error C2440: '=' : cannot convert from 'int' to 'struct pcap *'
Conversion from integral type to pointer type requires
reinterpret_cast, C-style cast or function-style cast
Line 109:
if((handler = pcap_open(udevice->name, 65536,
PCAP_OPENFLAG_PROMISCUOUS, 1000, NULL, errbuf)) == NULL)
Handler is declared as:
pcap_t *handler;
Thanks for your help

Sounds like this is expecting to be compiled as C++ and not plain C.

I am starting a project for an internship off on a bad foot. I need to
use WinPCap for my program and even after including pcap.h, I am
getting errors that things are undefined. I completely followed the
tutorial source in the documentation too!
Compiling...

Error executing cl.exe.
Here is my include chain:
#include <pcap.h> // pcap functions
#include <iostream.h> // basic io
#include <fstream.h> // file io
#include <string.h> // string funcs
Am I doing something wrong? I placed all of the include files in VC's
include file too....
Thanks.
