RFC: support other protocol families

[santigimeno]

I'm studying how to modify this module to support other protocol families apart from AF_UNIX while still using SOCK_DGRAM. I have 2 options: 1) copy most of the code from this module and replace the functionality related to AF_UNIX . 2) Try to make most of the code independent of the protocol family so any protocol family can easily be added.

Does this sound reasonable? Does trying #2 make any sense?

In this PR I've tried to accomplish this for bind, connect and sendto. I'm still trying to figure out a simple way to implement the reception. What do you think?

Thanks

const sockaddr*?

@bnoordhuis done. Thanks for the review. Does this change make sense to you?

When I find a satisfactory way to handle the reception will come back here.

If you're asking if I object to it, I don't. :-)

Apropos style, can you wrap long lines at 80 columns? Cheers.

Yeah, that was my question :-). Thanks.

Will do

Wrapped to 80 and rebased to master

@bnoordhuis Reception implementation.
In OnRecv I have initialized the whole sockaddr_storage to 0 as it was simpler than trying to make an implementation to initialize sockaddr_un

[santigimeno]

rebased to current master

Sorry, I've completely forgotten about this. I don't have much time to work on this module but if you want, I'll make you a collaborator.

[santigimeno]

@bnoordhuis Thanks for the offer. ATM I don't have time to work on this functionality but can help maintaining this module if you think you need some help.

[bnoordhuis]

More maintainers can't hurt. I'll add you to the repo. If you give me your npm handle, I'll give you publish rights as well.

[santigimeno]

npm handle: sgimeno
Thanks

[bnoordhuis]

Done.
