C Stack

[pepito]

How can I add a STACK to program writen in C, using GCC-LD to compile it?

Thank you

Do you have a stub that calls your c code? If so, you can add assembly code to setup the stack. Basically with the nasm assembler, you would do:

mov esp, stack
stack: resd 1024         ; allocate 1024 bytes for the stack

Then if you use bochs, you can use the bochs debugger to print the contents of the stack for you.

Hope this helps.

Really, I need a stack for each application written for my OS because the 'task manager' need the ss/esp values to create a process. I need to know where C creates the application's stack.

By now, as you say, I add an ASM file with the line 'times 4096 db 0' at the end of the application, but maybe exist another stack into the C program compiled with GCC.

Thank you for your response,

P.D. How can I print the contents of the stack using bochs?

...police department? Don't you mean "PS" (Postscript)?
