I create a dialog based application.
In OnInitDialog() function I try to get NIC information:
// TODO: Add extra initialization here
if (pcap_findalldevs(&alldevs, errbuf) == -1)
Here occur the access violation error.
In call stack I have only NDISNPP! 58214d4f(). So I don't know what is my app doing here. :-)
In disassembly window:
58214D4F cmp dword ptr [eax+ecx*4+18h],0
EAX = 00000000 EBX = 00000000
ECX = 7FF55FFB EDX = 5821E464
ESI = 0012BEF8 EDI = 000000B0
EIP = 58214D4F ESP = 01FEFFB8
EBP = 01FEFFEC EFL = 00000246 CS = 001B
DS = 0023 ES = 0023 SS = 0023 FS = 003B
GS = 0000 OV=0 UP=0 EI=1 PL=0 ZR=1 AC=0
FFD58004 = ????????
That's all I have after "if (pcap_findalldevs(&alldevs, errbuf) == -1)" string.
It happens on PC and notebook (Windows XP Professional SP2, NDISNPP.DLL has version 5.1.2600.2180, Winpcap version is 4.0.2 on both).
PC and notebook has one NIC.
I don't use COM/OLE.
