Title: Bare Command line arguments
Post by: macaswell on December 06, 2010, 03:57:31 PM

Okay,
   So I've written my OS out of nasm, Casnix OS/I (casnix.sourceforge.net).  Now I'm writing Casnix OS/II, and I'm stuck on a problem with the CLI portion of the kernel.
   I want to be able to pass command line arguments to a program.  I was thinking of moving the command line arguments into al, and have the program (cat in this case) pull al.

Example:

Code: [Select]

; =========================
; Casnix OS/II
; =========================

CLI call:
     mov al, cmd_line
     call os_load_file

CAT call:
     mov bx, al
     ; rest of code here

Would this work?  Has anyone else done something like this?

No.

Best,

No (I'm answering myself).  It depends on the kernel's method of memory management.

In my case, my [first] post is [partially] correct.  But still, no.
