Password protection and clear()

[Charles Quenneville]

Hello all!

I have 2 questions to ask you... First of all, I would like to restrict
the use of a program. I  let my friend use my account but I don't want
him to use a certain program. I thought of using a password protection.
As soon as he would type the name of that program, it would prompt him 
for a password. The only problem is that I am having a hard time 
implementing such a thing in my program. Could anyone help me out?

My second question concerns clear(); I have been trying to simply
write a program to clear my screen. Here is what I do:

#include <curses.h>

main(argc, argv)
{
 initscr();
 clear();
}

and this is how I compile: cc cl.c -o cl -lcurses -ltermcap

The result is always the same! NOTHING!! I've even tried wclear() but
no can do! 

When on a System V, no problems. but on the SparcStation1 we have, 
it doesn't work. We are running SunOS 4.1. I don't have the 
5lib/cc compiler. Can anyone help?!?!?

I thank you very much in advance
