f
fwprintf(3C) fwprintf(3C)
expanded with leading zeros. The default precision is 1. The result of converting 0 with
an explicit precision of 0 is no wide-characters.
X Behaves the same as the x
conversion wide-character except that letters ABCDEF are
used instead of abcdef.
f The double argument is converted to decimal notation in the style [-]ddd.ddd, where the
number of digits after the radix character is equal to the precision specification. If the
precision is missing, it is taken as 6; if the precision is explicitly 0 and no
# flag is
present, no radix character appears. If a radix character appears, at least one digit
appears before it. The value is rounded to the appropriate number of digits. The
fwprintf() family of functions may make available wide-character string representa-
tions for infinity and NaN.
e,E The double argument is converted in the style [-]d.ddde_dd, where there is one digit
before the radix character (which is non-zero if the argument is non-zero) and the
number of digits after it is equal to the precision; if the precision is missing, it is taken as
6; if the precision is 0 and no
# flag is present, no radix character appears. The value is
rounded to the appropriate number of digits. The
E conversion wide-character will pro-
duce a number with
E instead of
e introducing the exponent. The exponent always con-
tains at least two digits. If the value is 0, the exponent is 0. The fwprintf() family of
functions may make available wide-character string representations for infinity and
NaN.
g,G The double argument is converted in the style f or e (or in the style
E in the case of a G
conversion wide-character), with the precision specifying the number of significant digits.
If an explicit precision is 0, it is taken as 1. The style used depends on the value con-
verted; style
e (or E) will be used only if the exponent resulting from such a conversion is
less than -4 or greater than or equal to the precision. Trailing zeros are removed from
the fractional portion of the result; a radix character appears only if it is followed by a
digit. The fwprintf() family of functions may make available wide-character string
representations for infinity and NaN.
c If no l (ell) qualifier is present, the int argument is converted to a wide-character as if
by calling the btowc() function and the resulting wide-character is written. Otherwise
the wint_t argument is converted to wchar_t, and written.
s If no l (ell) qualifier is present, the argument must be a pointer to a character array con-
taining a character sequence beginning in the initial shift state. Characters from the
array are converted as if by repeated calls to the mbrtowc() function, with the conver-
sion state described by an mbstate_t object initialized to zero before the first character is
converted, and written up to (but not including) the terminating null wide-character. If
the precision is specified, no more than that many wide-characters are written. If the
precision is not specified or is greater than the size of the array, the array must contain a
null wide-character. If an
l (ell) qualifier is present, the argument must be a pointer to
an array of type wchar_t. Wide characters from the array are written up to (but not
including) a terminating null wide-character. If no precision is specified or is greater
than the size of the array, the array must contain a null wide-character. If a precision is
specified, no more than that many wide-characters are written.
p The argument must be a pointer to void. The value of the pointer is converted to a
sequence of printable wide-characters, in an implementation-dependent manner.
n The argument must be a pointer to an integer into which is written the number of wide-
characters written to the output so far by this call to one of the
fwprintf() functions.
No argument is converted.
C Same as lc.
S Same as ls.
% Output a % wide-character; no argument is converted. The entire conversion
specification must be %%.
APPLICATION USAGE
After
fwprintf() or wprintf() is applied to a stream, the stream becomes wide-oriented (see orien-
tation (5)).
