c++ - writing c code in a c++ app
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.
