          DESCRIPTION
               The logname function returns a pointer to the null-
               terminated login name; it extracts the LOGNAME environment
               variable from the user's environment.

               This routine is kept in /lib/libPW.a.

          FILES

          CAVEATS
               The return values point to static data whose content is
               overwritten by each call.

               This method of determining a login name is subject to for-
               gery.
