DESCRIPTION

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

Note:  The return value points to static data whose content is overwritten by
       each call.  This method of determining a login name is subject to
       forgery.  For better methods, see "cuserid,"  "getlogin," and "getpwent,
       getpwuid, getpwnam, setpwent, endpwent."
