Hi,we are working on a C/C++ application, where we can get calls from more than
one source.I am trying to capture packets and count the packets based on the
endpoint pair's e.g.A->BC->BD->Bas you can see, above we can get calls to B
from A,C and D and we would like to count individual bandwidth from A-> B,
A->C, A->DUser at any time can changes the endpoint pair as shown above, to
handle this scenariowe would like to reset the filter expression in
pcap_setfilter( ) after a given time(mostly 30 seconds)we were not able to find
anyway, to dynamically reset the filter expression and had to do it on our
ownwe are using pcap_loop with -1 option, which makes it run in infinite loop,
after every 30 seconds we are calling pcap_close( ) from the callback method
ofpcap_loop( ), as of now this causes a crash in the application. can someone
suggest a way to reset the filter expression?I looked on Google and found that
we can use pcap_breakloop( ) to terminate the infinite pcap_loop( )but
could not find any good pcap_breakloop( ) example.any help would be
appreciated.thanks,m
