Hi,

I have checked the forum and seems that noone has asked this question before.
I would like to ask what is difference between sockets in Linux and BSD ? (in terms of programming)

I think the data structure is different, but can someone advise me regarding this? How about Netlink API? Function calls?
Are they reusable?

I know that Linux and BSD are closely related and most of the codes are reusable.
My main concern is, can I throw a socket program that is working in BSD into Linux, compile it and expect it to work?

If not, what should i take note of?

Any kind of response will be greatly appreciated.
Thank you in advance.

Regards
Daryl

the sockets api is the same for linux and bsd at the user level. netlink is linux only, netgraph is bsd only. the raw sockets api is different, linux has LSF(linux socket filter) and packet sockets, bsd has BPF(berkely packet filter). other than that i can't think of anything else. any plain old sockets app, ie socket(), connect(), accept(), and so on will compile fine on both. the select() call is slightly different in regards to the timeout value and whether it gets changed,check out man page for that one.
