54.Sh DESCRIPTION
55The
56.Fn utempter_add_record
57and
58.Fn addToUtmp
59functions add a login record to the database for the TTY belonging to
60the pseudo-terminal master file descriptor
61.Fa fd ,
62using the username corresponding with the real user ID of the calling
63process and the optional hostname
64.Fa host .
65These functions are equivalent to
66.Xr ulog_login_pseudo 3 .
67.Pp
68The
69.Fn utempter_remove_record
70and
71.Fn removeLineFromUtmp
72functions mark the login session as being closed for the TTY belonging
73to the pseudo-terminal master file descriptor
74.Fa fd .
75These functions are equivalent to
76.Xr ulog_logout_pseudo 3 .
77.Pp
78The
79.Fn utempter_remove_added_record
80and
81.Fn removeFromUtmp
82functions have the same properties as the previously mentioned
83functions, except that they use an internally cached value of the file
84descriptor passed to the login functions.
85.Pp
86The
87.Fa pty
88arguments of
89.Fn addToUtmp
90and
91.Fn removeLineFromUtmp
92are unused.
