[Winpcap-users] pcap_dumper_t unable to load

[amruta tilaye]

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.
