The .Fn ulog_login function adds an entry for TTY .Fa line and username .Fa user . The .Fn ulog_login_pseudo function uses file descriptor to a pseudo-terminal master device .Fa fd to determine the TTY name, while using the username belonging to the real user ID of the calling process. The optional .Fa host argument denotes a remote hostname, in case the login session is provided by a network service. .Pp The .Fn ulog_logout and .Fn ulog_logout_pseudo functions mark the previously registered login session as being terminated. .Pp Because the .Fa line and .Fa user arguments of .Fn ulog_login and .Fn ulog_logout cannot be trusted, these functions require administrative privileges. The .Fn ulog_login_pseudo and .Fn ulog_logout_pseudo functions spawn a privileged process to perform the actual logging. .Sh SEE ALSO .Xr getuid 2 , .Xr posix_openpt 2 , .Xr ptsname 3 , .Xr pututxline 3 .Sh HISTORY These functions appeared in .Fx 9.0 .
