[Winpcap-users] How to break the pcap_loop

[Steighton_Haley at McAfee.com]

I would make the following suggestions:

1) pcap_loop is deprecated and discouraged from use.  I recommend you
use the pcap_next_ex() function.

2) Read the documentation. It clearly outlines the situations in which
pcap_loop() will exit.  Specifically, when an error occurs, or when
'count' packets are received)... your count is 0, which isn't addressed
in the docs, it says a -1 will cause the system to loop forever, or at
least until an error occurs).
