valid locale object handle.
Ordinary characters in

s without conversion.
Conversion specifiers are introduced by a _zsingle_quotesz_%_zsingle_quotesz_ character.
Immediately following it there can be zero or more of the

fis used as the numeric fill character (to be used with a left precision, see below). When not specified, the space character is used.
Do not use any grouping characters that might be defined for the current locale. By default, grouping is enabled.
The ( flag indicates that negative amounts should be enclosed between parentheses. The + flag indicates that signs should be handled in the default way, that is, amounts are preceded by the locale_zsingle_quotesz_s sign indication, for example, nothing for positive, − for negative.
Omit the currency symbol.
Left justify all fields. The default is right justification.
Next, there may be a field width: a decimal digit string specifying a minimum field width in bytes. The default is 0. A result smaller than this width is padded with spaces (on the left, unless the left-justify flag was given).
Next, there may be a left precision of the form # followed by a decimal digit string. If the number of digits left of the radix character is smaller than this, the representation is padded on the left with the numeric fill character. Grouping characters are not counted in this field width.
Next, there may be a right precision of the form .
followed by a decimal digit string. The amount being
formatted is rounded to the specified number of digits prior
to formatting. The default is specified in the
int_frac_digits items of the current locale.
If the right precision is 0, no radix character is printed.
(The radix character here is determined by
LC_MONETARY, and may differ from that
Finally, the conversion specification must be ended with a conversion character. The three conversion characters are
(In this case, the entire specification must be exactly %%.) Put a _zsingle_quotesz_%_zsingle_quotesz_ character in the result string.
One argument of type double is converted using the locale_zsingle_quotesz_s international currency format.
One argument of type double is converted using the locale_zsingle_quotesz_s national currency format.
returns the number of characters placed in the array
s, not including the
terminating null byte, provided the string, including the
terminating null byte, fits. Otherwise, it sets
errno to E2BIG, returns −1, and the contents
of the array is undefined.
