+/** 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.
