[Winpcap-users] pcap_freealldevs() causing program crash.

Did you also check that you aren't calling CDevice::Cleanup multiple times on the same "devs" pointer (thus trying to free the adapters list multiple times)?

Have a nice day

  Does anyone know why, whenever I put in "pcap_freealldevs(devs);" into my cleanup code (that frees all the memory, etc...that my program uses), it always crashes?

  devs declaration:
  pcap_if_t *devs, *d; // Device list

  My cleanup code:
  void CDevice::Cleanup(){

      // Free the device list

  and how I'm using devs:
  void CDevice::Devices(){
      if(pcap_findalldevs(&devs, error) == -1){
      } else{
          for(iCount = 0, d = devs; d != NULL; d = d->next, iCount++){
                  cDescription[iCount] = d->description;

              cDevice[iCount] = d->name;

  I've been racking my brain for over an hour trying to figure out what I'm doing.

  (Note: I call Cleanup() in the WM_DESTROY Windows message)
