There is important information about booting non-ack images in docs/UPDATING. ack/aout-format images can't be built any more, and booting clang/ELF-format ones is a little different. Updating to the new boot monitor is recommended. Changes in this commit: . drop boot monitor -> allowing dropping ack support . facility to copy ELF boot files to /boot so that old boot monitor can still boot fairly easily, see UPDATING . no more ack-format libraries -> single-case libraries . some cleanup of OBJECT_FMT, COMPILER_TYPE, etc cases . drop several ack toolchain commands, but not all support commands (e.g. aal is gone but acksize is not yet). . a few libc files moved to netbsd libc dir . new /bin/date as minix date used code in libc/ . test compile fix . harmonize includes . /usr/lib is no longer special: without ack, /usr/lib plays no kind of special bootstrapping role any more and bootstrapping is done exclusively through packages, so releases depend even less on the state of the machine making them now. . rename nbsd_lib* to lib* . reduce mtree

.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.
