rewinddir in windows? simple question

[Anon]

i have 2 functions.

if the first is called it changes the directory to:
chdir("users/$selected/$selected2/");

if the second is called:
chdir("users/$selected/$selected2/tn/");

now fails because the directory has been moved forward.

this is a basic question i know:
but how do i reset the directory at the end of a function?
how do i go back?

rewinddir("/"); does not seem to work.
the docs are not clear on this.

I just want to reset the directory at the end of a function. Thank you.

Use getcwd() at the top of the function to get the current working directory.
Then move to whatever directory you need,
and at the end of the function move to the directory you got from getcwd() at the beginning of the function.
