[tcpdump-workers] Influence of pcap_open_live parameters on pcap_sendpacket

[Doktor Bernd]

Hi,
 
I am trying to optimize my program by adjusting the parameters of 
pcap_open_live().
 
In my program, I am opening the same interface twice and use one handle in a 
thread for capturing packets and the other handle in a second thread for writing
 
Two questions:
- Do the two pcap_open_live() calls influence the hardware in anyway and have 
side effects on each other or are they bound to the handle and I can rely on 
the parameters I give to be set?
- Do the parameters influence pcap_sendpacket() in any way? From the 
documentation I assume that they are only for capturing from that interface.
 
All the best,
Bernd                                     -
