.Sh DESCRIPTION
|
|
The
|
|
.Fn getlastlogx
|
|
function looks up the entry for the user with user id
|
|
.Fa uid
|
|
in the
|
|
.Xr lastlogx 5
|
|
file given by
|
|
.Fa fname
|
|
and returns it in
|
|
.Fa \&ll .
|
|
If the provided
|
|
.Fa \&ll
|
|
is
|
|
.Dv NULL ,
|
|
the necessary space will be allocated by
|
|
.Fn getlastlogx
|
|
and should be
|
|
.Fn free Ns d
|
|
by the caller.
|
|
.Pp
|
|
The
|
|
.Fn getutmp
|
|
function fills out the entries in the struct utmp
|
|
.Fa u
|
|
with the data provided in the struct utmpx
|
|
.Fa ux .
|
|
.Fn getutmpx
|
|
does the opposite, filling out the entries in the struct utmpx
|
|
.Fa ux
|
|
with the data provided in the struct utmp
|
|
.Fa u ,
|
|
and initializing all the unknown fields to 0.
|
|
The sole exception is the
|
|
.Fa ut_type
|
|
field, which will be initialized to
|
|
.Dv USER_PROCESS .
|
|
.Pp
|
|
The
|
|
.Fn updlastlogx
|
|
function tries to update the information for the user with the user id
|
|
.Fa uid
|
|
in the
|
|
.Xr lastlogx 5
|
|
file given by
|
|
.Fa fname
|
|
with the data supplied in
|
|
.Fa \&ll .
|
|
A
|
|
.Ft struct lastlogx
|
|
is defined like this:
|
|
.Bd -literal
|
|
struct lastlogx {
|
|
struct timeval ll_tv; /* time entry was created */
|
|
char ll_line[_UTX_LINESIZE]; /* tty name */
|
|
char ll_host[_UTX_HOSTSIZE]; /* host name */
|
|
struct sockaddr_storage ll_ss; /* address where entry was made from */
|
|
};
|
|
.Ed
|
|
All the fields should be filled out by the caller.
|
|
.Pp
|
|
The
|
|
.Fn updwtmpx
|
|
function updates the
|
|
.Xr wtmpx 5
|
|
file
|
|
.Fa file
|
|
with the
|
|
.Xr utmpx 5
|
|
entry
|
|
.Fa utx .
|
|
.Pp
|
|
The
|
|
.Fn utmpxname
|
|
function sets the default
|
|
.Xr utmpx 5
|
|
database file name to
|
|
.Fa fname .
|
|
.Sh RETURN VALUES
|
|
.Fn getlastlogx
|
|
returns the found entry on success, or
|
|
.Dv NULL
|
|
if it could not open the database, could not find an entry matching
|
|
.Fa uid
|
|
in there, or could not allocate the necessary space (in case
|
|
.Fa \&ll
|
|
was
|
|
.Dv NULL ) .
|
|
.Pp
|
|
.Fn utmpxname
|
|
returns 1 on success, or 0 if the supplied file name was too long or
|
|
did not end with
|
|
.Sq x .
|
|
.Pp
|
|
.Fn updlastlogx
|
|
and
|
|
.Fn updwtmpx
|
|
return 0 on success, or \-1 in case the database or file respectively
|
|
could not be opened or the data not written into it.
