use IOCTL's, a big learning curve is involved but thats the way everyone does it. I did write IOCTL code long time ago and I'll send it to you tomorrow, sorry but I dont have it with me here. and major numbers are the identifying number for your module, so when an ioctl is caught by the kernel it knows whom to give it to. beware of using an already used major number. /usr/src/linux/Documentation/magic-number.txt -- --------------------------- Netiquette -> http://www.dtcc.edu/cs/rfc1855.html http://tumbak.at.preempted.net --------------------------- _______________________________________________ General mailing list [email protected] http://mail.jolug.org/mailman/listinfo/general_jolug.org
