2010-03-24Fix Linux getlogin{_r,} implementationUlrich Drepper
The old implementation uses fd 0 to determine the login TTY. This was needed because using /dev/tty it is not possible to deduce the login TTY. For some time now there is the pseudo-file /proc/self/loginuid which directly helps us to find the user. Prefer using this file. It also works if stdin is closed, redirected, or re-opened.
