Hello,
I am having difficulties in writing a c++ prog that uses C code to send an icmp
packet (icmpapi.h, ipexport.h (used by icmpapi.h)). This is what my code looks
like so far:
-------------------------------------
#include <iostream>
#include <windows.h>
extern "C" {
#include <icmpapi.h>
}
int main(){
using namespace std;
HANDLE icmp;
icmp = IcmpCreateFile();
cout << "hello";
return 0;
}
________________________________________________
It compiles but then i get an error that says:
_______________________________________________
hello.obj(hello)
Error 42: Symbol Undefined _IcmpCreateFile 0
--- errorlevel 1
_______________________________________________
Before i added the:
extern "C"
I would get the error:
_____________________________________________________________________
hello.obj(hello)
Error 42: Symbol Undefined ?IcmpCreateFile YGPAXXZ (void *stdcall
IcmpCreateFile (void ))
--- errorlevel 1
_____________________________________________________________________
Any insight would be greatly appreciated. Is there a way to send a custom icmp
packet using C++ libraries? This might help some. The code for sending the
exact packet I need to send is already written in C for me, so ideally I would
like to write a C++ prog that does some extra work but also sends the icmp
packet (exactly as written in the already existing C code that I have).
Thank you,
David S

You have to link it together with the import library of icmp.dll. You can make the import library yourself. Start command prompt and type this: implib c:\apps\dm\lib\icmp.lib C:\WINNT\system32\icmp.dll (or C:\WINDOWS\system32\icmp.dll for winxp) Just link it together when you compile your source: dmc hello.cpp icmp.lib or if you just compile the source only (with the -c option) and you would like to link it yourself: link hello.obj icmp.lib In article <cugbdi$2ohp$1 digitaldaemon.com>, david says...Hello, I am having difficulties in writing a c++ prog that uses C code to send an icmp packet (icmpapi.h, ipexport.h (used by icmpapi.h)).

When i attempt: dmc hello.cpp icmp.lib it says: Error 43: Not a Valid Library File The file is in the 'lib' directory and it does indicate that its attempting to link the .lib file. Do I just have a bad .lib file? What about the icmp.dll file? Does the .lib file use the .dll file in the system32 folder? I have one in my system32 right now, so I am assuming I am ok there.
