/** The fprintf function writes output to the stream pointed to by stream,
under control of the string pointed to by format that specifies how
subsequent arguments are converted for output. If there are insufficient
arguments for the format, the behavior is undefined. If the format is
exhausted while arguments remain, the excess arguments are evaluated
(as always) but are otherwise ignored. The fprintf function returns when
the end of the format string is encountered.
The format shall be a multibyte character sequence, beginning and ending in
its initial shift state. The format is composed of zero or more directives:
ordinary multibyte characters (not %), which are copied unchanged to the
output stream; and conversion specifications, each of which results in
fetching zero or more subsequent arguments, converting them, if applicable,
according to the corresponding conversion specifier, and then writing the
result to the output stream.
Each conversion specification is introduced by the character %. After
the %, the following appear in sequence:
- Zero or more flags (in any order) that modify the meaning of the
conversion specification.
- An optional minimum field width. If the converted value has fewer
characters than the field width, it is padded with spaces (by default)
on the left (or right, if the left adjustment flag, described later,
has been given) to the field width. The field width takes the form of
an asterisk * (described later) or a nonnegative decimal integer.
- An optional precision that gives the minimum number of digits to appear
for the d, i, o, u, x, and X conversions, the number of digits to
appear after the decimal-point character for e, E, f, and F
conversions, the maximum number of significant digits for the g and G
conversions, or the maximum number of bytes to be written for s
conversions. The precision takes the form of a period (.) followed
either by an asterisk * (described later) or by an optional decimal
integer; if only the period is specified, the precision is taken as
zero. If a precision appears with any other conversion specifier, the
behavior is undefined.
- An optional length modifier that specifies the size of the argument.
- A conversion specifier character that specifies the type of conversion
to be applied.
As noted above, a field width, or precision, or both, may be indicated by
an asterisk. In this case, an int argument supplies the field width or
precision. The arguments specifying field width, or precision, or both, shall
appear (in that order) before the argument (if any) to be converted. A negative
field width argument is taken as a - flag followed by a positive field width.
A negative precision argument is taken as if the precision were omitted.
The flag characters and their meanings are:
- The result of the conversion is left-justified within the field.
(It is right-justified if this flag is not specified.)
+ The result of a signed conversion always begins with a plus or
minus sign. (It begins with a sign only when a negative value is
converted if this flag is not specified.)
space If the first character of a signed conversion is not a sign, or
if a signed conversion results in no characters, a space is
prefixed to the result. If the space and + flags both appear, the
space flag is ignored.
# The result is converted to an "alternative form". For o
conversion, it increases the precision, if and only if necessary,
to force the first digit of the result to be a zero (if the value
and precision are both 0, a single 0 is printed). For x (or X)
conversion, a nonzero result has 0x (or 0X) prefixed to it. For e,
E, f, F, g, and G conversions, the result of converting a
floating-point number always contains a decimal-point character,
even if no digits follow it. (Normally, a decimal-point character
appears in the result of these conversions only if a digit follows
it.) For g and G conversions, trailing zeros are not removed from
the result. For other conversions, the behavior is undefined.
0 For d, i, o, u, x, X, e, E, f, F, g, and G conversions, leading
zeros (following any indication of sign or base) are used to pad to
the field width rather than performing space padding, except when
converting an infinity or NaN. If the 0 and - flags both appear,
the 0 flag is ignored. For d, i, o, u, x, and X conversions, if a
precision is specified, the 0 flag is ignored. For other
conversions, the behavior is undefined.
The length modifiers and their meanings are:
hh Specifies that a following d, i, o, u, x, or X conversion specifier
applies to a signed char or unsigned char argument (the argument
will have been promoted according to the integer promotions, but
its value shall be converted to signed char or unsigned char before
printing); or that a following n conversion specifier applies to a
pointer to a signed char argument.
h Specifies that a following d, i, o, u, x, or X conversion specifier
applies to a short int or unsigned short int argument (the argument
will have been promoted according to the integer promotions, but
its value shall be converted to short int or unsigned short int
before printing); or that a following n conversion specifier
applies to a pointer to a short int argument.
l (ell) Specifies that a following d, i, o, u, x, or X conversion
specifier applies to a long int or unsigned long int argument; that
a following n conversion specifier applies to a pointer to a long
int argument; that a following c conversion specifier applies to a
wint_t argument; that a following s conversion specifier applies to
a pointer to a wchar_t argument; or has no effect on a following e,
E, f, F, g, or G conversion specifier.
ll (ell-ell) Specifies that a following d, i, o, u, x, or X conversion
specifier applies to a long long int or unsigned long long int
argument; or that a following n conversion specifier applies to a
pointer to a long long int argument.
j Specifies that a following d, i, o, u, x, or X conversion specifier
applies to an intmax_t or uintmax_t argument; or that a following n
conversion specifier applies to a pointer to an intmax_t argument.
z Specifies that a following d, i, o, u, x, or X conversion specifier
applies to a size_t or the corresponding signed integer type
argument; or that a following n conversion specifier applies to a
pointer to a signed integer type corresponding to size_t argument.
t Specifies that a following d, i, o, u, x, or X conversion specifier
applies to a ptrdiff_t or the corresponding unsigned integer type
argument; or that a following n conversion specifier applies to a
pointer to a ptrdiff_t argument.
L Specifies that a following e, E, f, F, g, or G conversion specifier
applies to a long double argument.
If a length modifier appears with any conversion specifier other than as
specified above, the behavior is undefined.
The conversion specifiers and their meanings are:
d,i The int argument is converted to signed decimal in the style
[-]dddd. The precision specifies the minimum number of digits to
appear; if the value being converted can be represented in fewer
digits, it is expanded with leading zeros. The default precision
is 1. The result of converting a zero value with a precision of
zero is no characters.
o,u,x,X The unsigned int argument is converted to unsigned octal (o),
unsigned decimal (u), or unsigned hexadecimal notation (x or X) in
the style dddd; the letters abcdef are used for x conversion and
the letters ABCDEF for X conversion. The precision specifies the
minimum number of digits to appear; if the value being converted
can be represented in fewer digits, it is expanded with leading
zeros. The default precision is 1. The result of converting a zero
value with a precision of zero is no characters.
f,F A double argument representing a floating-point number is
converted to decimal notation in the style [-]ddd.ddd, where the
number of digits after the decimal-point character is equal to the
precision specification. If the precision is missing, it is taken
as 6; if the precision is zero and the # flag is not specified, no
decimal-point character appears. If a decimal-point character
appears, at least one digit appears before it. The value is rounded
to the appropriate number of digits.
A double argument representing an infinity is converted in one
of the styles [-]inf or [-]infinity - which style is
implementation-defined. A double argument representing a NaN is
converted in one of the styles [-]nan or [-]nan(n-char-sequence)
- which style, and the meaning of any n-char-sequence, is
implementation-defined. The F conversion specifier produces INF,
INFINITY, or NAN instead of inf, infinity, or nan, respectively.
e,E A double argument representing a floating-point number is
converted in the style [-]d.ddd e[+-]dd, where there is one digit
(which is nonzero if the argument is nonzero) before the
decimal-point character 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 zero and the # flag is not specified, no
decimal-point character appears. The value is rounded to the
appropriate number of digits. The E conversion specifier produces a
number with E instead of e introducing the exponent. The exponent
always contains at least two digits, and only as many more digits
as necessary to represent the exponent. If the value is zero, the
exponent is zero.
A double argument representing an infinity or NaN is converted
in the style of an f or F conversion specifier.
g,G A double argument representing a floating-point number is
converted in style f or e (or in style F or E in the case of a G
conversion specifier), depending on the value converted and the
precision. Let P equal the precision if nonzero, 6 if the precision
is omitted, or 1 if the precision is zero. Then, if a conversion
with style E would have an exponent of X:
- if P > X = -4, the conversion is with style f (or F) and
precision P - (X + 1).
- otherwise, the conversion is with style e (or E) and
precision P - 1.
Finally, unless the # flag is used, any trailing zeros are removed
from the fractional portion of the result and the decimal-point
character is removed if there is no fractional portion remaining.
A double argument representing an infinity or NaN is converted in
the style of an f or F conversion specifier.
c If no l length modifier is present, the int argument is
converted to an unsigned char, and the resulting character is
written. If an l length modifier is present, the wint_t argument is
converted as if by an ls conversion specification with no precision
and an argument that points to the initial element of a two-element
array of wchar_t, the first element containing the wint_t argument
to the lc conversion specification and the second a null wide
character.
s If no l length modifier is present, the argument is a pointer
to the initial element of an array of character type. Characters
from the array are written up to (but not including) the
terminating null character. If the precision is specified, no more
than that many bytes are written. If the precision is not specified
or is greater than the size of the array, the array shall contain a
null character.
If an l length modifier is present, the argument shall be a
pointer to the initial element of an array of wchar_t type. Wide
characters from the array are converted to multibyte characters
(each as if by a call to the wcrtomb function, with the conversion
state described by an mbstate_t object initialized to zero before
the first wide character is converted) up to and including a
terminating null wide character. The resulting multibyte characters
are written up to (but not including) the terminating null
character (byte). If no precision is specified, the array shall
contain a null wide character. If a precision is specified, no more
than that many bytes are written (including shift sequences, if
any), and the array shall contain a null wide character if, to
equal the multibyte character sequence length given by the
precision, the function would need to access a wide character one
past the end of the array. In no case is a partial multibyte
character written.
p The argument shall be a pointer to void. The value of the
pointer is converted to a sequence of printing characters, in an
implementation-defined manner.
n The argument shall be a pointer to signed integer into which is
written the number of characters written to the output stream so
far by this call to fprintf. No argument is converted, but one is
consumed. If the conversion specification includes any flags, a
field width, or a precision, the behavior is undefined.
% A % character is written. No argument is converted. The
complete conversion specification shall be %%.
In no case does a nonexistent or small field width cause truncation of a
field; if the result of a conversion is wider than the field width, the
field is expanded to contain the conversion result.
@param[in] stream An open File specifier to which the output is sent.
@param[in] format A multi-byte character sequence containing characters
to be copied unchanged, and conversion specifiers
which convert their associated arguments. Copied and
converted characters are sent to the output stream.
@param ... Variable number of parameters as required by format.
@return The fprintf function returns the number of characters
transmitted, or a negative value if an output or encoding
error occurred.
