There is a known issue with forward declarations of some types in the pcap 
include files that cause this exception.

Subject: [Winpcap-users] pcap_dumper_t unable to load


> Hi guys,
>
>  I'm trying to store the packets captured to "savefile" using 
> pcap_dump_open and pcap_dump functions.  Both these functions use pointer 
> to pcap_dumper_t structure called dumpfile.
>
>  I'm working in Visual Studio .NET 2003 MFC Console application (.NET). 
> And I'm getting following assembly error:
>  An unhandled exception of type 'System.TypeLoadException' occurred in 
> Unknown Module.
>  Additional information: Could not load type pcap_dumper from assembly 
> try, Version=1.0.2303.25936, Culture=neutral, PublicKeyToken=null.

>  The error points to
>  mainret = main(argc, argv, envp);
>  in crtexe.c file.

>  This is the related piece of code:
>  pcap_dumper_t* dumpfile;
>  char* tmpdir;
>  .
>  .
>  tmpdir = strdup(tmpnam(NULL));
>  dumpfile =pcap_dump_open(adhandle,"dumpfile"); >>>adhandle is return 
> value

>  >>of pcap_open structure
>  if(dumpfile==NULL)
>  {
>  fprintf(stderr,"\nError opening output file\n");
>  return -1;
>  }
>  .
>  .
>  pcap_loop(adhandle, 0, packet_handler, (unsigned char *)dumpfile);
>  .
>  .
>  I'm unable to debug this. All other functions work fine. So I guess there 
> is no linking error. It's only when I use pcap_dumper_t I'm getting error.
