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
|
|
.Nm
|
|
functions manipulate stringlists, which are lists of
|
|
strings that extend automatically if necessary.
|
|
.Pp
|
|
The
|
|
.Ar StringList
|
|
structure has the following definition:
|
|
.Bd -literal -offset indent
|
|
typedef struct _stringlist {
|
|
char **sl_str;
|
|
size_t sl_max;
|
|
size_t sl_cur;
|
|
} StringList;
|
|
.Ed
|
|
.Pp
|
|
where:
|
|
.Bl -tag -width "sl_str" -offset indent
|
|
.It Ar sl_str
|
|
is a pointer to the base of the array containing the list,
|
|
.It Ar sl_max
|
|
is the size of
|
|
.Ar sl_str ,
|
|
and
|
|
.It Ar sl_cur
|
|
is the offset in
|
|
.Ar sl_str
|
|
of the current element.
|
|
.El
|
|
.Pp
|
|
The following stringlist manipulation functions are available:
|
|
.Bl -tag -width "sl_delete()" -offset 2n
|
|
.It Fn sl_init
|
|
Create a stringlist.
|
|
Returns a pointer to a
|
|
.Ar StringList ,
|
|
or
|
|
.Dv NULL
|
|
in case of failure.
|
|
.It Fn sl_free
|
|
Releases memory occupied by
|
|
.Ar sl
|
|
and the
|
|
.Ar sl-\*[Gt]sl_str
|
|
array.
|
|
If
|
|
.Ar freeall
|
|
is non-zero, then each of the items within
|
|
.Ar sl-\*[Gt]sl_str
|
|
is released as well.
|
|
.It Fn sl_add
|
|
Add
|
|
.Ar item
|
|
to
|
|
.Ar sl-\*[Gt]sl_str
|
|
at
|
|
.Ar sl-\*[Gt]sl_cur ,
|
|
extending the size of
|
|
.Ar sl-\*[Gt]sl_str .
|
|
Returns zero upon success, \-1 upon failure.
|
|
.It Fn sl_find
|
|
Find
|
|
.Ar item
|
|
in
|
|
.Ar sl ,
|
|
returning
|
|
.Dv NULL
|
|
if it's not found.
|
|
.It Fn sl_delete
|
|
Remove
|
|
.Ar item
|
|
from the list.
|
|
If
|
|
.Ar freeit
|
|
is non-zero, the string is freed.
|
|
Returns
|
|
.Dv 0
|
|
if the name is found
|
|
and
|
|
.Dv \-1
|
|
if the name is not found.
