I would like to create a new system call with the help of process manager whick accepts an integer and prints its square.
Please any help

Hi,

Are you sure you mean a system call, and not, say, a program? Creating a new system call would require creating and loading a kernel module. It would also have nothing to do with your process manager.

Now, given the open nature of Linux, this is entirely possible, but I suspect that anyone getting in to kernel hacking would know enough to a) know about /usr/src/linux-headers-* b) know how to find this info on his/her own.

So in summation, confirm that you really want to create a system call, and not a program. Then use Google, or your favorite alternative search engine.


PS - Is this a school homework assignment? If so, go earn your own damn degree.
Edit: By the list of other posts by this user, it sure looks like it.

If your definition of a 'system call' means anything that is available on the commandline (also called console, terminal, shell), then you need something like:

Can you please post your homework assignment verbatim?
The question is rather ambiguous.

Oh, wait, you're not allowed to post homework questions,
even less so in Greek. Silly me.



Cheers,
