  37   38  .sp
  38   39  .LP
  39   40  The \fBgetlogin()\fR function returns a pointer to the login name as found in
  40   41  \fB/var/adm/utmpx\fR. It can be used in conjunction with \fBgetpwnam\fR(3C) to
  41   42  locate the correct password file entry when the same user \fBID\fR is shared by
  42   43  several login names.
  43   44  .sp
  44   45  .LP
       46 +The login name plus the terminating null byte can be up to 33 characters
       47 +in length.  For programs that call \fBgetlogin()\fR and expect only the
       48 +legacy 9-character length, the user compatibility library
       49 +\fB/usr/lib/getlogin8.so.1\fR truncates long login names to fit a
       50 +9-character buffer.  This library should be added to such an application
       51 +at runtime using \fBLD_PRELOAD\fR.
       52 +.sp
       53 +.LP
  45   54  If \fBgetlogin()\fR is called within a process that is not attached to a
  46   55  terminal, it returns a null pointer. The correct procedure for determining the
  47   56  login name is to call \fBcuserid\fR(3C), or to call \fBgetlogin()\fR and if it
  48   57  fails to call \fBgetpwuid\fR(3C).
  49   58  .sp
  50   59  .LP
  51   60  The \fBgetlogin_r()\fR function has the same functionality as \fBgetlogin()\fR
  52   61  except that the caller must supply a buffer \fIname\fR with length
  53   62  \fInamelen\fR to store the result.  The \fIname\fR buffer must be at least
  54   63  \fB_POSIX_LOGIN_NAME_MAX\fR bytes in size (defined in <\fBlimits.h\fR>). The
