anyone know how to use the fcb?

anyone know where i can find some docs on using the fcb? i was working on rewriting some of the c++ libraries in assembly for a project im working on, ive got almost everything but i cant figure out how to get the length of a file. ive looked everywhere, but no one seems to remember how to use an fcb, only that thats a good place to find what im looking for. any help would be much appreciated... i dont know how much longer my coffee stash can hold out.

Try going here.

I don't have any of my old assembly source but this looks like I remember it.

2 maxtor 60gig ata100 drives

Suse 7.1(god gnome is crappy compared to CDE)/win2000 based system

wow, thats a nice page. my question though is how on earth do i read the thing? where is it stored? that page as with every other doc ive read: skips right over that part. i know im missing something really simple here. anyone know maybe where i can find some old source for a really simple program that uses the fcb?

It is actually in the file itself.

I will help you more later, but I have to run....

Ok. The fcb is something mostly used by the interrupts, not so much directly. So when you call interrupt 29 or whatever then it will make use of it.

It's one of the interupts in the high 20 something range id DOS. I am not even sure those are supported anymore in windows, though.

You will probably have to get a book on assembly. As a programmer it is a sometimes annoying fact of life - I have dozens of books I needed just to accomplish one dopy project and haven't cracked open since, many on esoteric or senseless topics.

Hopefully you are getting paid enough that getting a book you need is not a hardship. If not, then you should be able to get them to get it for you or give you a raise, if you are sure you need it.
