linux int 0x80

Post by kubeos »

Hello,

On this page http://www.ctyme.com/intr/int-21.htm is a fairly detailed look at DOS system calls. It's what I was using to add dos support to kube. But since I'm now working in pmode I'm looking for something similar for linux int 80h system calls. Does anyone know a good page with details on the registers going in and out of the the interrupt. I tried googling but didn't find anything as detailed as I needed.

Thanks everyone.

hi,

this is quite good. You could also look into the sourcecode. It is well commented. The site I gave you lists the files you could additionally look at.

i hate to use this verb... but "googling" it would have been far easier. "linux system call" brings up one of these responses and would have saved me the energy of saying, next time, google it.

Allow me to rephrase... Google Harder!! The first time i went looking for OS Development it hardly existed, i found my first helpful topics on pages 20+.
