.Nd "log a new login record to the utmp and wtmp files"
|

.Sh LIBRARY

.Sh SYNOPSIS
|
|
.Fd #include <sys/types.h>
|
|
.Fd #include <utmp.h>
|

.Fn login "struct utmp *ut"
|
|
.Sh DESCRIPTION
|
|
The function
|
|
.Fn 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
|
|
None.
|
|
.Sh SEE ALSO
|
|
.Xr logout 3 ,
|
|
.Xr ttyslot 3 ,
|
|
.Xr utmp 5 ,
|
|
.Xr wtmp 5
|
|
.Sh BUGS
|
|
The interface provided by
|
|
.Fn login
|
|
is rather crude. The caller must know about the details of a
|
|
.Va struct utmp .
|
|
Some better abstraction needs to be worked out.
