  Subject: [Winpcap-users] Code for unhandled exceptation error


  Here is my code,However i think problem is not from code because even when i make it short to open only the file i will get same error.Another thing is that evrytime i open my file in a project i have to go to project menu and settings to set manually the wincap.lib ,in this way there is no error in buil process but in run time i will get myfilename.exe error and in reports shows that message;unhandled exceptation

  #include "pcap.h"
  #include <stdio.h>
  #include <stdlib.h>
  #include <iostream>
  using namespace std;
  #define LINE_LEN 16
  void find_device(pcap_if_t **all_devices);
   main(int argc, char **argv) {
          int res,i=0;
    struct pcap{};
          char errbuf[PCAP_ERRBUF_SIZE];    /* Error string */
          
    struct pcap_pkthdr *header; /* The header that pcap gives us */
    struct pcap_pkthdr *pcap_header;
    const u_char *packet;  /* The actual packet */
    pcap_t *handle;   /* Session handle */
          char error[PCAP_ERRBUF_SIZE];
          FILE *capfile;
          char *capture_file;
    char *pkt_data;
          int caplen;
           
           pcap_t *pcap_open_offline(char *scapturefile,char *errbuf);
            
      /* Grab a packet
          int code  = pcap_next_ex(handle,&header,&packet);
          if (code < 0)
                  cout << "Error in pcap_next_ex\n";

          cout << "length of packet is" << header->len << " bytes\n"; 
          printf("%ld: \n", header->len);

          /* And close the session 
          pcap_close(handle);
          return(0); */
    /* Retrieve the packets from the file */
      while((res = pcap_next_ex( handle, &header, &packet)) >= 0){
          /* print pkt timestamp and pkt len */
          printf("%ld:%ld (%ld)\n", header->ts.tv_sec, header->ts.tv_usec, header->len);          
          
          /* Print the packet */
          for (i=1; (i < header->caplen + 1 ) ; i++)
          {
              printf("%.2x ", pkt_data[i-1]);
              if ( (i % LINE_LEN) == 0) printf("\n");
          }        
          printf("\n\n");     
      }    
      if(res == -1){
          printf("Error reading the packets: %s\n", pcap_geterr(handle));
      }
      
      return 0;
  }
