* login/logout.c (logout): Do nothing if getutline_r returns ESRCH. * login/pututline_r.c (pututline_r): Since we assign RESULT from lseek now, check that it's >= 0, not == 0. Wed Jul 3 13:28:04 1996 Miles Bader <miles@gnu.ai.mit.edu> * login/login.c (login): Make a copy of *UT, fill in various fields that we supply (ut_line, ut_type, ut_pid), and use the copy in place of UT. * login/getutline_r.c (getutline_r): When we return ESRCH, mark UTMP_DATA->ubuf invalid (by setting UTMP_DATA->loc_utmp to 0).
