function devel_switch_user

Switches to a different user.

We don't call session_save_session() because we really want to change users. Usually unsafe!

Parameters

string $name: The username to switch to, or NULL to log out.

./devel.module, line 1475

        $user = $account;
        $user->timestamp = time() - 9999;
        if (!$old_uid) {
            // Switch from anonymous to authorized.
