- Fix for possible unset uid/gid in toproto
- Fix for default mtree style
- Update libelf
- Importing libexecinfo
- Resynchronize GCC, mpc, gmp, mpfr
- build.sh: Replace params with show-params.
This has been done as the make target has been renamed in the same
way, while a new target named params has been added. This new
target generates a file containing all the parameters, instead of
printing it on the console.
- Update test48 with new etc/services (Fix by Ben Gras <ben@minix3.org)
get getservbyport() out of the inner loop

.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
