SubjectRe: STREAMS: interface versus implementation
   Date: 	Tue, 15 Sep 1998 20:26:18 -0400
From: Zack Weinberg <zack@rabi.columbia.edu>

The functions that look like they need some kernel help are:

getpmsg putpmsg isastream fattach fdetach (latter three map to ioctls)

open("/dev/foo") for foo = tcp, udp, maybe arp, icmp, ip, eth

ioctl(fd, I_xyz, data) for various I_xyz ioctls. (Many of these just
need to do nothing and return 0 instead of failing with -ENOSYS.)

As a suggestion, if you haven't done so already, identify one or more
(preferably more) user-mode programs which use the STREAMS interface ---
not the TLI interface --- before you embark on this project. That way,
you'll have a benchmark to work against and test against.
