Thread: Testing super user

i want test if current user super user. think root super user. true that, root super user?

here simple algorithm:

code:

#include <iostream> #include <string> #include <cstdlib> using namespace std;  int main() {         string name = getenv("user");         if(name == "root") cout << "super user\n";         else cout << "not super user\n";         return 0; }

i pretty sure not way. can tell me how can current user super user or not.

in advance.

ha! don't use user comparisons; environment variable can spoofed.

use geteuid() or getuid() instead. tend see applications use former.
