Reentrant version of getlogin function, specified in P1003.1c/D6. Stub version. * sysdeps/unix/getlogin.c (getlogin): Use ttyname_r instead of ttyname. This avoids saving and restoring the old content. Also use setutent_r, getutline_r and endutent_r instead of accing UTMP file directly. * sysdeps/unix/getlogin_r.c: New file. Reentrant version of getlogin function, specified in P1003.1c/D6. Tue Jun 4 20:10:09 1996 J.T.
