Date: Fri, 16 Feb 2001 08:10:44 -0800 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.5.2650.21) Content-Type: text/plain Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Please excuse my newbie question... I've been fooling around with module programing on 2.4.0, and I've made this little module for a char device that printk's (darn, my kernel log's growing real huge now!!!) anything I redirect into /dev/charmod (Hurray! I made my first module).... I have not yet implemented any read facilities, yet.... and here's my question: What's IOCTL? What do I need it for? Oh BTW, I have this dumb little idea (please flame me if it's stupid...)... Here goes: I want to create a small database system (possibly using ANSI-SQL92??) that's integrated into the kernel... I think I'd make a module for a char device, which would be used for comm' with the database and a module for a filesystem (which I'd have to come up with) that would hold the database... Do any of you think such a database would be faster than other database systems? Please tell me what you people think about this...
