       call and set the value of before calling The service module's  function
       will  then call to prompt for the user name. Note that certain PAM ser‐
       vice modules (such as a smart card module) may override	the  value  of
       and pass in their own prompt.

       Applications  that  call multiple times should set the value of to NULL
       with before calling if they want the user to be prompted for a new user
       name each time.

       The  value  of  user retrieved by should not be modified or freed.  The
       item will be released by
