memory resident program

[usuthar]

hi friends,
i want to make memory resident program which resides as background process in windows and linux...
how do i go for that?

if you want to do it in windows, windows is multitasking, so any program that you make (and properly hide from the user ) would do the trick.

As for Linux, I don't have any experience at all, but I've heard that it's multitasking too, so I assume that you can do the same thing that in Windows

if you want to use DOS, that's more challenging!, because you have to call an interrupt (I dont remember which one) and do some other things (I once did it, but I can't ebember how it's done)

check out fork and execve system calls to create processes in linux and running different programs on these processes.
