The
strfmon() function places characters into the array pointed to by
s as controlled by the string pointed to by
format. No more than
maxsize bytes are placed into the array.
The format string is composed of zero or more directives: ordinary characters (not
%), 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
% character. After the
%, the following appear in sequence:
•
Zero or more of the following flags:
=f
A ‘=' character followed by another character f which is used as the numeric fill character.
^
Do not use grouping characters, regardless of the current locale default.
+
Represent positive values by prefixing them with a positive sign, and negative values by prefixing them with a negative sign. This is the default.
(
Enclose negative values in parentheses.
!
Do not include a currency symbol in the output.
-
Left justify the result. Only valid when a field width is specified.
•
An optional minimum field width as a decimal number. By default, there is no minimum width.
•
A ‘#' sign followed by a decimal number specifying the maximum expected number of digits after the radix character.
•
A ‘.' character followed by a decimal number specifying the number of digits after the radix character.
•
One of the following conversion specifiers:
i
The double argument is formatted as an international monetary amount.
n
