If I am correct, bpfattach is the kernel-level function. And you're

Yes. I am trying to write a program to capture from an interface and
inject them to another, kind of like bcrelay functionality in poptop
[http://www.poptop.org/]
If you're trying to capture packets, you'll probably want to
consult the pcap(3) manual page.
Thanks! Does it support injecting packets into an interface?
hmmm have a look at netgraph
at least some of the following node types may be useful to you,
and writing new ones is easy.

ng_atmpif(4), ng_bluetooth(4), ng_bpf(4), ng_bridge(4), ng_bt3c(4),
ng_btsocket(4), ng_cisco(4), ng_device(4), ng_echo(4), ng_eiface(4),
