Hi Friend,

Thanx for u r quick response.

elaburate what you mean to say.

The reason why we have put continue after each pcap_freealldevs is that in case of any error it will go back to fetching the device list.

  I'm not sure but I think the code logic is wrong. I would recommend you to put pcap_freealldevs(allDevs); 
  call before each continue statement.

    Hi All, 

    We are using WinPcap 3.0 to create an application, the problem wwhich we are encountering is after 32 loops pcap_findalldevs() starts returning 0 adapters.

    We are simply counting the available adapters after 1/2 seconds . Following is the code which we are using.Kindly advise why after approx 32 loops it starts returning 0 adapters.
