On Windows, WinPcap provodes the pcap_getevent() (http://winpcap.polito.it/docs/docs31beta4/html/group__wpcapfunc.html#ga37) function, that does something similar to pcap_get_selectable_fd(). I ask, by the way, if the two functions could be unified in some way. > Will I lose (gain) efficiency if I use one thread instead of > many- i.e. > can I start missing packets at high load? As usual when you go multithread, performance depends on a lot of factors: how well you distribute the load, how complex the code is in the two cases, the cache usage, and so on.
