• an optional h specifying that a following
d, i, o, u, x or X conversion wide-character
applies to a type short int or type unsigned short int argument (the argument will have
been promoted according to the integral promotions, and its value will be converted to type
short int or unsigned short int before printing)
• an optional
hh specifying that a following

signed char or unsigned char argument ( the argument will have been promoted according
to the integer promotions, but its value will be converted to short or unsigned short before
printing)

hh specifying that a following
n conversion specifier applies to a pointer to a
signed char argument

5. A conversion wide-character that indicates the type of conversion to be applied.
A field width, or precision, or both, may be indicated by an asterisk (*). In this case an argument of type
int supplies the field width or precision. Arguments specifying field width,orprecision, or both must
appear in that order before the argument, if any, to be converted. A negative field width is taken as a
-
flag followed by a positive field width. A negative precision is taken as if the precision were omitted. In for-
mat wide-character strings containing the
%n$ form of a conversion specification, a field width or precision
may be indicated by the sequence
%n$, where m is a decimal integer in the range [1, {NL_ARGMAX}]
giving the position in the argument list (after the format argument) of an integer argument containing the
field width or precision, for example:
wprintf(L"%1$d:%2$. *3$d:%4$, *3$d\n", hour, min, precision, sec);
The format can contain either numbered argument specifications (that is, %n$ and *m$), or unnumbered
argument specifications (that is, % and *), but normally not both. The only exception to this is that %% can
be mixed with the %n$ form. The results of mixing numbered and unnumbered argument specifications in
a format wide-character string are undefined. When numbered argument specifications are used, specify-
ing the Nth argument requires that all the leading arguments, from the first to the (N-1)th, are specified in
the format wide-character string.
The flag wide-characters and their meanings are:
’ The integer portion of the result of a decimal conversion (%i, %d, %u, %g, or %G ) will be
formatted with thousands’ grouping wide-characters. For other conversions the behavior is
undefined. The non-monetary grouping wide-character is used.
