[Kylix] How do I determine the home directory?

How can I determine programatically what the current "home" directory is?  I tried this:

procedure TForm1.Button1Click(Sender: TObject);
begin
  with TStringList.Create do
  begin
    Clear;
    Add('This is a test!');
    SaveToFile('~/TestFile.txt');
    Free;
  end;
end;
In UNIX/Linux, the "~/" should represent the user's home directory.  However, Kylix doesn't seem to see it that way.  I then tried replacing the "~/TestFile.txt" with "/home/edsteele/TestFile.txt" and that worked.  The problem is that if another person runs the program, this won't be their home directory.

The value of the current user's home directory is stored in an environment variable called "HOME".  Barring a better solution, how can I read the value of environment variables?

Thanks,
Eric

hi,
here are a couple of examples i found :

//to read the environment var
getenv("HOME")


// to read it from etc/passwd
procedure TForm1.Button1Click(Sender: TObject);
var
  ppwd :PPasswordRecord;
begin
  ppwd := getpwuid( getuid() );
  Caption := ppwd^.pw_dir;
end;

After your direction, I found the function I was looking for.  It is actually called GetEnvironmentVariable().  I didn't get a chance to try the second solution yet.  Thanks for the help, I'm sure I will have more.  :)
