Silyaev" To: hackers@freebsd.org Subject: Multiple instances of the same character device Message-ID: <19991211173336.A635@jupiter.delta.ny.us> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii X-Mailer: Mutt 1.0i Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG The question is very simple. Is it possible to open the same character pseudo device, for example /dev/foo0, simultaneously from other programs, and to work with this instances independently? I'm asked as the developer of a driver with such requirements, so please don't complain about such technique. I read some discursion about this in the mailing list http://www.FreeBSD.org/cgi/getmsg.cgi?fetch=854845+857264+/usr/local/www/db/text/1997/freebsd-hackers/19970727.freebsd-hackers . But it's old one (dated by begin of '97). -- Vladimir Silyaev To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
