It is the first one I found (I didn't like raw gdb either). It isn't perfect but it sure makes code development a little easier. Depending on what you are doing, there is also the possibility of using something like RHIDE which is an integrated development environment similar to the old Borland IDE. Cheers! Kevin.

My main aim is to understand the workings of the kernel a little bit better. For this reason I would like to verify what is stored in the first few hundred memory locations. e.g in x202 the signature HdrS is supposed to be stored. So to answer your question: Any which way that would get me on the screen the memory content of preselected locations would do. Jing Su has pointed out one way to accomplish this. My C programming is rusty and it will therefore take some time to follow up his lead. Any other suggestion will be very much appreciated. Thanks, John -- The Toronto Linux Users Group.

Your commandline starts to look something like this (yes, I have but one IDE channel, so hdb is my burner): cdrecord dev=ATAPI:/dev/hdb speed=24 image.iso I installed XCDRoast the other day. I'm not sure if I put the ATAPI configuration bit in a magic file somewhere months ago, or if it was smart enough to see the IDE burner for what it was. It "just worked". Next I'd like to see cdrdao have ATAPI support, though I haven't caught myself wanting to burn any VCDs lately -- taa Science is but a perversion of itself unless it has as its ultimate goal the betterment of humanity. --Nikola Tesla /*eof*/ -- The Toronto Linux Users Group.

As it turns out, I'm too stupid (well, too impatient really) to use gdb by itself. I'd prefer something that gave a listing of the source code on the screen, showed the currently-executing line, etc. There seems to be about 18,732 different gdb front-ends out there.

C programming question

If you are programming in C you can go down to the assembler level and issue a BIOS interrupt (sorry I don't recall the number) to write to a particular disk location. DOS interrupt 25H allows you to write to a particular disk sector, but seeing that this is the TLUG Mailing list, I don't imagine that's of much help to you. Jim. -----Original Message----- From: John Wildberger [mailto:wildberger-iRg7kjdsKiH3fQ9qLvQP4Q at public.gmane.org] Sent: Friday, December 19, 2003 8:19 AM To: tlug-lxSQFCZeNF4 at public.gmane.org Subject: [TLUG]: C programming question To open a file for reading precludes to know the filename.
