I think the idea is to <br>
a) copy the string for(i = 0 ; etc)<br>
b) call freealldevs()<br>
If you try to access the pointer d->name after the call to
freealldevs() bad things *will* happen. Not sure if that is what you
are doing<br>

Have a very nice day.<br>

Yup. What I do, is store the info like so:<br>
<br>
cDevice[iCount] = d->name;<br>
<br>
Then, when I goto list the info, I do this:<br>
<br>
for(i = 0; i < iCount; i++){<br>
m_devices.AddString(cDevice[i]);<br>
}<br>
<br>
(m_devices is a ListBox)<br>

MqX: Thanks, but it's still causing me trouble (I really appreciate it
though).<br>

You're not referring to the devices after the pcap_freealldevs() call, <br>
right?<br>
