 The \fBgetlogin()\fR function returns a pointer to the login name as found in
 \fB/var/adm/utmpx\fR. It can be used in conjunction with \fBgetpwnam\fR(3C) to
 locate the correct password file entry when the same user \fBID\fR is shared by
 several login names.

 The \fBgetlogin_r()\fR function has the same functionality as \fBgetlogin()\fR
 except that the caller must supply a buffer \fIname\fR with length \fInamelen\fR

 Upon successful completion, \fBgetlogin()\fR returns a pointer to the login
