Address of PATH variable
I want to find the address of the PATH environment variable. What is the best way to go about finding that address? Does the address of the PATH variable ever change, or is it constant?

#include<stdio.h>
#include<unistd.h>
extern char **environ;

int main() {
        printf("environp: %p\n", environ);
}

But don't know if its right...

And one more thing... When I'm trying the same on a Virtual Machine, the address doesn't change but it is giving me a constant address for the environment variable... Is there any specific reason for this?
