hey, i was wonder if anyone knows how to enable root permission to execute a segment of code which needs root access. The code is as follows

if (kill(pid,SIGKILL) != 0) {
g_warning ("Could not signal cardmgr");
}

The kill function is what needs the root permission. HElp..

There are a couple of possibilities right off the bat:

(1) execute the program as root.
(2) set the program to be setuid root (dangerous, but fairly common).

Note that what you are trying to do is to stop a process that you do not own, which is a security breach. Of course, sometimes there are good reasons to bend the security a bit.

Hope this helps.

Ok, well I realized that I did not want to actually kill the cardmgr i simply want to request a card eject signal but this still requires root access. Is there someway I can prompt the user to enter the root password to allow the eject request to be sent as a root process?

this function that i will theoretically make, would catch the signal request response to prompt the user for tht root password and allow the request to be a root process instead.

i have also enclosed a pic of the beta program.

PS. I would hope that there is a function (s) in C that will allow me to do so.

Well, you can just stop the pcmcia service by this command set:
service pcmcia stop
<remove card>
service pcmcia start
<the second is to restart the second card if there>

you should be able to set up permissions to allow service pcmcia to be started and stopped by regular users. I have to admit that I'm not sure how right off the top of my head because I don't have linux on a laptop.
