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 SYNOPSIS
|
|
.In monetary.h
|
|
.Ft ssize_t
|
|
.Fn strfmon "char * restrict s" "size_t maxsize" "const char * restrict format" "..."
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Fn strfmon
|
|
function places characters into the array pointed to by
|
|
.Fa s
|
|
as controlled by the string pointed to by
|
|
.Fa format .
|
|
No more than
|
|
.Fa maxsize
|
|
bytes are placed into the array.
|
|
.Pp
|
|
The format string is composed of zero or more directives:
|
|
ordinary characters (not
|
|
.Cm % ) ,
|
|
which are copied unchanged to the output stream; and conversion
|
|
specifications, each of which results in fetching zero or more subsequent
|
|
arguments.
|
|
Each conversion specification is introduced by the
|
|
.Cm %
|
|
character.
|
|
After the
|
|
.Cm % ,
|
|
the following appear in sequence:
|
|
.Bl -bullet
|
|
.It
|
|
Zero or more of the following flags:
|
|
.Bl -tag -width "XXX"
|
|
.It Cm = Ns Ar f
|
|
A
|
|
.Sq Cm =
|
|
character followed by another character
|
|
.Ar f
|
|
which is used as the numeric fill character.
|
|
.It Cm ^
|
|
Do not use grouping characters, regardless of the current locale default.
|
|
.It Cm +
|
|
Represent positive values by prefixing them with a positive sign,
|
|
and negative values by prefixing them with a negative sign.
|
|
This is the default.
|
|
.It Cm \&(
|
|
Enclose negative values in parentheses.
|
|
.It Cm \&!
|
|
Do not include a currency symbol in the output.
|
|
.It Cm \-
|
|
Left justify the result.
|
|
Only valid when a field width is specified.
|
|
.El
|
|
.It
|
|
An optional minimum field width as a decimal number.
|
|
By default, there is no minimum width.
|
|
.It
|
|
A
|
|
.Sq Cm #
|
|
sign followed by a decimal number specifying the maximum
|
|
expected number of digits after the radix character.
|
|
.It
|
|
A
|
|
.Sq Cm \&.
|
|
character followed by a decimal number specifying the number
|
|
of digits after the radix character.
|
|
.It
|
|
One of the following conversion specifiers:
|
|
.Bl -tag -width "XXX"
|
|
.It Cm i
|
|
The
|
|
.Vt double
|
|
argument is formatted as an international monetary amount.
|
|
.It Cm n
|
|
The
|
|
.Vt double
|
|
argument is formatted as a national monetary amount.
|
|
.It Cm %
|
|
A
|
|
.Sq Li %
|
|
character is written.
|
|
.El
|
|
.El
|
|
.Sh RETURN VALUES
|
|
If the total number of resulting bytes including the terminating
|
|
.Dv NULL
|
|
byte is not more than
|
|
.Fa maxsize ,
|
|
.Fn strfmon
|
|
returns the number of bytes placed into the array pointed to by
|
|
.Fa s ,
|
|
not including the terminating
|
|
.Dv NULL
|
|
byte.
|
|
Otherwise, \-1 is returned,
|
|
the contents of the array are indeterminate,
|
|
and
|
|
.Va errno
|
|
is set to indicate the error.
|
|
.Sh ERRORS
|
|
The
|
|
.Fn strfmon
|
|
function will fail if:
|
|
.Bl -tag -width Er
|
|
.It Bq Er E2BIG
|
|
Conversion stopped due to lack of space in the buffer.
|
|
.It Bq Er EINVAL
|
|
The format string is invalid.
|
|
.It Bq Er ENOMEM
|
