Link with

on the

.Xr cc 1

|

|
|
.Sh DESCRIPTION
|
||
|
|
The function
|
||
|
|
.Nm login
|
||
|
|
records the
|
||
|
|
.Ar ut
|
||
|
|
entry being passed into the appropriate slot of the
|
||
|
|
.Xr utmp 5
|
||
|
|
file (according to the controlling terminal of the calling process),
|
||
|
|
and appends it to the
|
||
|
|
.Xr wtmp 5
|
||
|
|
file. The calling process must have permission to write to both files.
|
||
|
|
.Sh RETURN VALUES
|
||
|
|

|
.Sh BUGS
|
||
|
|
The interface provided by
|
||
|
|
.Nm login
|
||
|
|
is rather crude. The caller must know about the details of a
|
||
|
|
.Va struct utmp .
|
||
|
|
Some better abstraction needs to be worked out.
