+The login name plus the terminating null byte can be up to 33 characters
+in length.  For programs that call \fBgetlogin()\fR and expect only the
+legacy 9-character length, the user compatibility library
+\fB/usr/lib/getlogin8.so.1\fR truncates long login names to fit a
+9-character buffer.  This library should be added to such an application
+at runtime using \fBLD_PRELOAD\fR.

 If \fBgetlogin()\fR is called within a process that is not attached to a
 terminal, it returns a null pointer. The correct procedure for determining the
 login name is to call \fBcuserid\fR(3C), or to call \fBgetlogin()\fR and if it
 fails to call \fBgetpwuid\fR(3C).
