[Winpcap-users] Crash with non existent device name

[Rohan Sen]

Hi All,

Recently I upgraded one my app which used to WinPcap 3.1 to 4.0.
I replaced by pcap_open_live() api call with pcap_open().

After this change I noticed that if the device indicated by 'source'
argument does not exist the latest version of WinPcap
throws exception whereas the earlier version used to return -1 and I was
able to indicate the error to use and exit.

My call to pcap_open() is as follows:

  fp = pcap_open(ifName,
                 65536,
                 /* We do not want to get the packet we sent */
                 PCAP_OPENFLAG_PROMISCUOUS|PCAP_OPENFLAG_NOCAPTURE_LOCAL,
                 1,
                 NULL,
                 errBuf);

I would really appreciate if someone could point me if any additional
check/function call is
necessary to avoid the exception.
