Questions on pcap.h
 

I'm studying packet capturing with pcap.h.

Does anyone know where I can find information about the pro and con of pcap.h?

Are there alternative libraries I can use to capture packet instead of using pcap.h?

now that pcap use the Linux Socket Filter instead of emulating BPF in user space, i cant think of any reason not to use it.

I'm not talking about using pcap or not.

Just trying to analyze it, so looking for info relates to its pro and con.
And checking if there are alternative library to capture packet other than pcap.h
