Add a libutempter compatibility interface to libulog. The ulog_login_pseudo(3) and ulog_logout_pseudo(3) interfaces provide a functionality identical to what libutempter has to offer. Just transform libutempter's calls into the before mentioned functions. libutempter doesn't work with utmpx, so instead of fixing I thought the easiest way would be to integrate this functionality. libutempter is used by applications like xterm and the KDE libraries, so if I ever change the underlying file format, these applications will keep working automatically. Also increase __FreeBSD_version to indicate the addition (as well as the import of libulog).

mdoc: order prologue macros consistently by Dd/Dt/Os Although groff_mdoc(7) gives another impression, this is the ordering most widely used and also required by mdocml/mandoc. Reviewed by: ru Approved by: philip, ed (mentors)

.Nm addToUtmp ,

.Nd utempter compatibility interface
.Sh LIBRARY
.Lb libulog
.Sh SYNOPSIS
.In utempter.h
.Ft int
.Fn utempter_add_record "int fd" "const char *host"
.Ft int
.Fn utempter_remove_added_record "void"
.Ft int
.Fn utempter_remove_record "int fd"
.Ft void
.Fn addToUtmp "const char *pty" "const char *host" "int fd"
.Ft void
.Fn removeFromUtmp "void"
.Ft void
.Fn removeLineFromUtmp "const char *pty" "int fd"
.Sh DESCRIPTION
The
.Fn utempter_add_record
and
.Fn addToUtmp
functions add a login record to the database for the TTY belonging to
the pseudo-terminal master file descriptor
.Fa fd ,
using the username corresponding with the real user ID of the calling
process and the optional hostname
.Fa host .
These functions are equivalent to
.Xr ulog_login_pseudo 3 .
.Pp
The
.Fn utempter_remove_record
and
.Fn removeLineFromUtmp
functions mark the login session as being closed for the TTY belonging
to the pseudo-terminal master file descriptor
.Fa fd .
These functions are equivalent to
.Xr ulog_logout_pseudo 3 .
.Pp
The
.Fn utempter_remove_added_record
and
.Fn removeFromUtmp
functions have the same properties as the previously mentioned
functions, except that they use an internally cached value of the file
descriptor passed to the login functions.
.Pp
The
.Fa pty
arguments of
.Fn addToUtmp
and
.Fn removeLineFromUtmp
are unused.
.Sh RETURN VALUES
In this implementation, the
.Fn utempter_add_record ,
.Fn utempter_remove_added_record
and
.Fn utempter_remove_record
always return a value of 0.
.Sh SEE ALSO
Remove utmpx stub from libulog. I'm not increasing the shlib major version for this, because not a single application outside the base system should have used these functions in such a short timespan. Rewrite ulog_login(3) and ulog_logout(3) to build on top of the utmpx implementation in libc.
