DESCRIPTION
<<printf>> accepts a series of arguments, applies to each a
format specifier from <<*<[format]>>>, and writes the
formatted data to <<stdout>>, terminated with a null character.
The behavior of <<printf>> is undefined if there are not enough
arguments for the format.
<<printf>> returns when it reaches the end of the format string.
If there are more arguments than the format requires, excess
arguments are ignored.
formatted data to <<stdout>>, without a terminating NUL
character. The behavior of <<printf>> is undefined if there
are not enough arguments for the format. <<printf>> returns
when it reaches the end of the format string. If there are
more arguments than the format requires, excess arguments are
ignored.
<<fprintf>>, <<asprintf>>, <<sprintf>> and <<snprintf>> are identical
to <<printf>>, other than the destination of the formatted output:
<<fprintf>> sends the output to a specified file <[fd]>, while
<<asprintf>> stores the output in a dynamically allocated buffer,
while <<sprintf>> stores the output in the specified char array
<[str]> and <<snprintf>> limits number of characters written to
<[str]> to at most <[size]> (including terminating <<0>>). For
<<sprintf>> and <<snprintf>>, the behavior is undefined if the
output <<*<[str]>>> overlaps with one of the arguments. For
<<asprintf>>, <[strp]> points to a pointer to char which is filled
in with the dynamically allocated buffer. <[format]> is a pointer
to a charater string containing two types of objects: ordinary
characters (other than <<%>>), which are copied unchanged to the
output, and conversion specifications, each of which is introduced
by <<%>>. (To include <<%>> in the output, use <<%%>> in the format
string.) A conversion specification has the following form:
<<fprintf>> is like <<printf>>, except that output is directed
to the stream <[fd]> rather than <<stdout>>.
. %[<[flags]>][<[width]>][.<[prec]>][<[size]>][<[type]>]
<<sprintf>> is like <<printf>>, except that output is directed
to the buffer <[str]>, and a terminating NUL is output.
Behavior is undefined if more output is generated than the
buffer can hold.
The fields of the conversion specification have the following meanings:
<<snprintf>> is like <<sprintf>>, except that output is
limited to at most <[size]> bytes, including the terminating
<<NUL>>. As a special case, if <[size]> is 0, <[str]> can be
NULL, and <<snprintf>> merely calculates how many bytes would
be printed.
<<asprintf>> is like <<sprintf>>, except that the output is
stored in a dynamically allocated buffer, <[pstr]>, which
should be freed later with <<free>>.
<<asnprintf>> is like <<sprintf>>, except that the return type
is either the original <[str]> if it was large enough, or a
dynamically allocated string if the output exceeds *<[size]>;
the length of the result is returned in *<[size]>. When
dynamic allocation occurs, the contents of the original
<[str]> may have been modified.
For <<sprintf>>, <<snprintf>>, and <<asnprintf>>, the behavior
is undefined if the output <<*<[str]>>> overlaps with one of
the arguments. Behavior is also undefined if the argument for
<<%n>> within <<*<[format]>>> overlaps another argument.
<[format]> is a pointer to a character string containing two
types of objects: ordinary characters (other than <<%>>),
which are copied unchanged to the output, and conversion
specifications, each of which is introduced by <<%>>. (To
include <<%>> in the output, use <<%%>> in the format string.)
A conversion specification has the following form:
. %[<[pos]>][<[flags]>][<[width]>][.<[prec]>][<[size]>]<[type]>
The fields of the conversion specification have the following
meanings:
O+
o <[pos]>
Conversions normally consume arguments in the order that they
are presented. However, it is possible to consume arguments
out of order, and reuse an argument for more than one
conversion specification (although the behavior is undefined
if the same argument is requested with different types), by
specifying <[pos]>, which is a decimal integer followed by
'$'. The integer must be between 1 and <NL_ARGMAX> from
limits.h, and if argument <<%n$>> is requested, all earlier
arguments must be requested somewhere within <[format]>. If
positional parameters are used, then all conversion
specifications except for <<%%>> must specify a position.
o <[flags]>
an optional sequence of characters which control
output justification, numeric signs, decimal points,
trailing zeroes, and octal and hex prefixes.
The flag characters are minus (<<->>), plus (<<+>>),
space ( ), zero (<<0>>), and sharp (<<#>>). They can
appear in any combination.
<[flags]> is an optional sequence of characters which control
output justification, numeric signs, decimal points, trailing
zeros, and octal and hex prefixes. The flag characters are
minus (<<->>), plus (<<+>>), space ( ), zero (<<0>>), sharp
(<<#>>), and quote (<<'>>). They can appear in any
combination, although not all flags can be used for all
conversion specification types.
o+
o '
Since newlib only supports the C locale, this
flag has no effect in this implementation.
But in other locales, when <[type]> is <<i>>,
<<d>>, <<u>>, <<f>>, <<F>>, <<g>>, or <<G>>,
the locale-dependent thousand's separator is
inserted prior to zero padding.
o -
The result of the conversion is left justified, and the right is
padded with blanks. If you do not use this flag, the result is right
justified, and padded on the left.
The result of the conversion is left
justified, and the right is padded with
blanks. If you do not use this flag, the
result is right justified, and padded on the
left.
o +
The result of a signed conversion (as determined by <[type]>)
will always begin with a plus or minus sign. (If you do not use
this flag, positive values do not begin with a plus sign.)
The result of a signed conversion (as
determined by <[type]> of <<d>>, <<i>>, <<a>>,
<<A>>, <<e>>, <<E>>, <<f>>, <<F>>, <<g>>, or
<<G>>) will always begin with a plus or minus
sign. (If you do not use this flag, positive
values do not begin with a plus sign.)
o " " (space)
If the first character of a signed conversion specification
is not a sign, or if a signed conversion results in no
characters, the result will begin with a space. If the
space ( ) flag and the plus (<<+>>) flag both appear,
the space flag is ignored.
If the first character of a signed conversion
specification is not a sign, or if a signed
conversion results in no characters, the
result will begin with a space. If the space
( ) flag and the plus (<<+>>) flag both
appear, the space flag is ignored.
o 0
If the <[type]> character is <<d>>, <<i>>, <<o>>, <<u>>,
<<x>>, <<X>>, <<e>>, <<E>>, <<f>>, <<g>>, or <<G>>: leading zeroes,
are used to pad the field width (following any indication of sign or
base); no spaces are used for padding. If the zero (<<0>>) and
minus (<<->>) flags both appear, the zero (<<0>>) flag will
be ignored. For <<d>>, <<i>>, <<o>>, <<u>>, <<x>>, and <<X>>
conversions, if a precision <[prec]> is specified, the zero (<<0>>)
flag is ignored.
If the <[type]> character is <<d>>, <<i>>,
<<o>>, <<u>>, <<x>>, <<X>>, <<a>>, <<A>>,
<<e>>, <<E>>, <<f>>, <<g>>, or <<G>>: leading
zeros are used to pad the field width

the zero (<<0>>) flag will be ignored. For
<<d>>, <<i>>, <<o>>, <<u>>, <<x>>, and <<X>>
conversions, if a precision <[prec]> is
specified, the zero (<<0>>) flag is ignored.
Note that <<0>> is interpreted as a flag, not as the beginning
of a field width.

o <[width]>
<[width]> is an optional minimum field width. You can either
specify it directly as a decimal integer, or indirectly by
using instead an asterisk (<<*>>), in which case an <<int>>
argument is used as the field width. Negative field widths
are not supported; if you attempt to specify a negative field
width, it is interpreted as a minus (<<->>) flag followed by a
positive field width.
<[width]> is an optional minimum field width. You can
either specify it directly as a decimal integer, or
indirectly by using instead an asterisk (<<*>>), in
which case an <<int>> argument is used as the field
width. If positional arguments are used, then the
width must also be specified positionally as <<*m$>>,
with m as a decimal integer. Negative field widths
are treated as specifying the minus (<<->>) flag for
left justfication, along with a positive field width.
The resulting format may be wider than the specified
width.
o <[prec]>
an optional field; if present, it is introduced with `<<.>>'
(a period). This field gives the maximum number of
characters to print in a conversion; the minimum number of
digits of an integer to print, for conversions with <[type]>
<<d>>, <<i>>, <<o>>, <<u>>, <<x>>, and <<X>>; the maximum number of
significant digits, for the <<g>> and <<G>> conversions;
or the number of digits to print after the decimal
point, for <<e>>, <<E>>, and <<f>> conversions. You can specify
<[prec]> is an optional field; if present, it is
introduced with `<<.>>' (a period). You can specify
the precision either directly as a decimal integer or
indirectly by using an asterisk (<<*>>), in which case
an <<int>> argument is used as the precision. Supplying a negative
precision is equivalent to omitting the precision.
If only a period is specified the precision is zero.
If a precision appears with any other conversion <[type]>
than those listed here, the behavior is undefined.
an <<int>> argument is used as the precision. If
positional arguments are used, then the precision must
also be specified positionally as <<*m$>>, with m as a
decimal integer. Supplying a negative precision is
equivalent to omitting the precision. If only a
period is specified the precision is zero. The effect
depends on the conversion <[type]>.
o+
o d, i, o, u, x, or X
Minimum number of digits to appear. If no
precision is given, defaults to 1.
o a or A
Number of digits to appear after the decimal
point. If no precision is given, the
precision defaults to the minimum needed for
an exact representation.
o e, E, f or F
Number of digits to appear after the decimal
point. If no precision is given, the
precision defaults to 6.
o g or G
Maximum number of significant digits. A
precision of 0 is treated the same as a
precision of 1. If no precision is given, the
precision defaults to 6.
o s or S
Maximum number of characters to print from the
string. If no precision is given, the entire
string is printed.
o all others
undefined.
o-
o <[size]>
<<h>>, <<l>>, and <<L>> are optional size characters which
override the default way that <<printf>> interprets the
data type of the corresponding argument. <<h>> forces
the following <<d>>, <<i>>, <<o>>, <<u>>, <<x>> or <<X>> conversion
<[type]> to apply to a <<short>> or <<unsigned short>>. <<h>> also
forces a following <<n>> <[type]> to apply to
a pointer to a <<short>>. Similarily, an
<<l>> forces the following <<d>>, <<i>>, <<o>>, <<u>>,
<<x>> or <<X>> conversion <[type]> to apply to a <<long>> or
<<unsigned long>>. <<l>> also forces a following <<n>> <[type]> to
apply to a pointer to a <<long>>. <<l>> with <<c>>, <<s>> is
equivalent to <<C>>, <<S>> respectively. If an <<h>>
or an <<l>> appears with another conversion
specifier, the behavior is undefined. <<L>> forces a
following <<e>>, <<E>>, <<f>>, <<g>> or <<G>> conversion <[type]> to
apply to a <<long double>> argument. If <<L>> appears with
any other conversion <[type]>, the behavior is undefined.
<[size]> is an optional modifier that changes the data
type that the corresponding argument has. Behavior is
unspecified if a size is given that does not match the
<[type]>.
o+
o hh
With <<d>>, <<i>>, <<o>>, <<u>>, <<x>>, or
<<X>>, specifies that the argument should be
converted to a <<signed char>> or <<unsigned
char>> before printing.
With <<n>>, specifies that the argument is a
pointer to a <<signed char>>.
o h
With <<d>>, <<i>>, <<o>>, <<u>>, <<x>>, or
<<X>>, specifies that the argument should be
converted to a <<short>> or <<unsigned short>>
before printing.
With <<n>>, specifies that the argument is a
pointer to a <<short>>.
o l
With <<d>>, <<i>>, <<o>>, <<u>>, <<x>>, or
<<X>>, specifies that the argument is a
<<long>> or <<unsigned long>>.
With <<c>>, specifies that the argument has
type <<wint_t>>.
With <<s>>, specifies that the argument is a
pointer to <<wchar_t>>.
With <<n>>, specifies that the argument is a
pointer to a <<long>>.
With <<a>>, <<A>>, <<e>>, <<E>>, <<f>>, <<F>>,
<<g>>, or <<G>>, has no effect (because of
vararg promotion rules, there is no need to
distinguish between <<float>> and <<double>>).
o ll
With <<d>>, <<i>>, <<o>>, <<u>>, <<x>>, or
<<X>>, specifies that the argument is a
<<long long>> or <<unsigned long long>>.
With <<n>>, specifies that the argument is a
pointer to a <<long long>>.
o j
With <<d>>, <<i>>, <<o>>, <<u>>, <<x>>, or
<<X>>, specifies that the argument is an
<<intmax_t>> or <<uintmax_t>>.
With <<n>>, specifies that the argument is a
pointer to an <<intmax_t>>.
o z
With <<d>>, <<i>>, <<o>>, <<u>>, <<x>>, or
<<X>>, specifies that the argument is a
<<ssize_t>> or <<size_t>>.
With <<n>>, specifies that the argument is a
pointer to a <<ssize_t>>.
o t
With <<d>>, <<i>>, <<o>>, <<u>>, <<x>>, or
<<X>>, specifies that the argument is a
<<ptrdiff_t>>.
With <<n>>, specifies that the argument is a
pointer to a <<ptrdiff_t>>.
o L
With <<a>>, <<A>>, <<e>>, <<E>>, <<f>>, <<F>>,
<<g>>, or <<G>>, specifies that the argument
is a <<long double>>.
o-
o <[type]>
<[type]> specifies what kind of conversion <<printf>> performs.
Here is a table of these:
<[type]> specifies what kind of conversion <<printf>>
performs. Here is a table of these:
o+
o %
prints the percent character (<<%>>)
Prints the percent character (<<%>>).
o c
prints <[arg]> as single character
Prints <[arg]> as single character. If the
<<l>> size specifier is in effect, a multibyte
character is printed.
o C
prints wchar_t <[arg]> as single multibyte character
Short for <<%lc>>.
o s
prints characters until precision is reached or a null terminator
is encountered; takes a string pointer
Prints the elements of a pointer to <<char>>
until the precision or a null character is
reached. If the <<l>> size specifier is in
effect, the pointer is to an array of
<<wchar_t>>, and the string is converted to
multibyte characters before printing.
o S
converts wchar_t characters to multibyte output characters until
precision is reached or a null wchar_t terminator
is encountered; takes a wchar_t pointer
Short for <<%ls>>.
o d
prints a signed decimal integer; takes an <<int>> (same as <<i>>)
o d or i
Prints a signed decimal integer; takes an
<<int>>. Leading zeros are inserted as
necessary to reach the precision. A precision
of 0 produces an empty string.
o i
prints a signed decimal integer; takes an <<int>> (same as <<d>>)
o D
Newlib extension, short for <<%ld>>.
o o
prints a signed octal integer; takes an <<int>>
Prints an unsigned octal integer; takes an
<<unsigned>>. Leading zeros are inserted as
necessary to reach the precision. A precision
of 0 produces an empty string.
o O
Newlib extension, short for <<%lo>>.
o u
prints an unsigned decimal integer; takes an <<int>>
Prints an unsigned decimal integer; takes an
<<unsigned>>. Leading zeros are inserted as
necessary to reach the precision. A precision
of 0 produces an empty string.
o U
Newlib extension, short for <<%lu>>.
o x
prints an unsigned hexadecimal integer (using <<abcdef>> as
digits beyond <<9>>); takes an <<int>>
Prints an unsigned hexadecimal integer (using
<<abcdef>> as digits beyond <<9>>); takes an
<<unsigned>>. Leading zeros are inserted as
necessary to reach the precision. A precision
of 0 produces an empty string.
o X
prints an unsigned hexadecimal integer (using <<ABCDEF>> as
digits beyond <<9>>); takes an <<int>>
Like <<x>>, but uses <<ABCDEF>> as digits
beyond <<9>>.
o f
prints a signed value of the form <<[-]9999.9999>>; takes
a floating-point number
Prints a signed value of the form
<<[-]9999.9999>>, with the precision
determining how many digits follow the decimal
point; takes a <<double>> (remember that
<<float>> promotes to <<double>> as a vararg).
The low order digit is rounded to even. If
the precision results in at most DECIMAL_DIG
digits, the result is rounded correctly; if
more than DECIMAL_DIG digits are printed, the
result is only guaranteed to round back to the
original value.
If the value is infinite, the result is
<<inf>>, and no zero padding is performed. If
the value is not a number, the result is
<<nan>>, and no zero padding is performed.
o F
Like <<f>>, but uses <<INF>> and <<NAN>> for
non-finite numbers.
o e
prints a signed value of the form <<[-]9.9999e[+|-]999>>; takes a
floating-point number
Prints a signed value of the form
<<[-]9.9999e[+|-]999>>; takes a <<double>>.
The digit before the decimal point is non-zero
if the value is non-zero. The precision
determines how many digits appear between
<<.>> and <<e>>, and the exponent always
contains at least two digits. The value zero
has an exponent of zero. If the value is not
finite, it is printed like <<f>>.
o E
prints the same way as <<e>>, but using <<E>> to introduce the
exponent; takes a floating-point number
Like <<e>>, but using <<E>> to introduce the
exponent, and like <<F>> for non-finite
values.
o g
prints a signed value in either <<f>> or <<e>> form, based on given
value and precision---trailing zeros and the decimal point are
printed only if necessary; takes a floating-point number
Prints a signed value in either <<f>> or <<e>>
form, based on the given value and
precision---an exponent less than -4 or
greater than the precision selects the <<e>>
form. Trailing zeros and the decimal point
are printed only if necessary; takes a
<<double>>.
o G
prints the same way as <<g>>, but using <<E>> for the exponent if an
exponent is needed; takes a floating-point number
Like <<g>>, except use <<F>> or <<E>> form.
o a
Prints a signed value of the form
<<[-]0x1.ffffp[+|-]9>>; takes a <<double>>.
The letters <<abcdef>> are used for digits
beyond <<9>>. The precision determines how
many digits appear after the decimal point.
The exponent contains at least one digit, and
is a decimal value representing the power of
2; a value of 0 has an exponent of 0.
Non-finite values are printed like <<f>>.
o A
Like <<a>>, except uses <<X>>, <<P>>, and
<<ABCDEF>> instead of lower case.
o n
stores (in the same object) a count of the characters written;
takes a pointer to <<int>>
Takes a pointer to <<int>>, and stores a count
of the number of bytes written so far. No
output is created.
o p
prints a pointer in an implementation-defined format.
This implementation treats the pointer as an
<<unsigned long>> (same as <<Lu>>).
o-
O-
Takes a pointer to <<void>>, and prints it in
an implementation-defined format. This
implementation is similar to <<%#tx>>), except
that <<0x>> appears even for the NULL pointer.
o-
O-
<<_printf_r>>, <<_fprintf_r>>, <<_asprintf_r>>,
<<_sprintf_r>>, <<_snprintf_r>>, <<_asnprintf_r>> are simply
reentrant versions of the functions above.
RETURNS
<<sprintf>> and <<asprintf>> return the number of bytes in the output string,
save that the concluding <<NULL>> is not counted.
<<printf>> and <<fprintf>> return the number of characters transmitted.
If an error occurs, <<printf>> and <<fprintf>> return <<EOF>> and
<<asprintf>> returns -1. No error returns occur for <<sprintf>>.
On success, <<sprintf>> and <<asprintf>> return the number of bytes in
the output string, except the concluding <<NUL>> is not counted.
<<snprintf>> returns the number of bytes that would be in the output
string, except the concluding <<NUL>> is not counted. <<printf>> and
<<fprintf>> return the number of characters transmitted.
<<asnprintf>> returns the original <[str]> if there was enough room,
otherwise it returns an allocated string.
If an error occurs, the result of <<printf>>, <<fprintf>>,
<<snprintf>>, and <<asprintf>> is a negative value, and the result of
<<asnprintf>> is NULL. No error returns occur for <<sprintf>>. For
<<printf>> and <<fprintf>>, <<errno>> may be set according to
<<fputc>>. For <<asprintf>> and <<asnprintf>>, <<errno>> may be set
to ENOMEM if allocation fails, and for <<snprintf>>, <<errno>> may be
set to EOVERFLOW if <[size]> or the output length exceeds INT_MAX.
PORTABILITY
The ANSI C standard specifies that implementations must
support at least formatted output of up to 509 characters.
ANSI C requires <<printf>>, <<fprintf>>, <<sprintf>>, and
<<snprintf>>. <<asprintf>> and <<asnprintf>> are newlib extensions.
The ANSI C standard specifies that implementations must support at
least formatted output of up to 509 characters. This implementation
has no inherent limit.
Depending on how newlib was configured, not all format specifiers are
supported.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.

DESCRIPTION
<<vprintf>>, <<vfprintf>>, <<vasprintf>>, <<vsprintf>> and <<vsnprintf>> are
(respectively) variants of <<printf>>, <<fprintf>>, <<asprintf>>, <<sprintf>>,
and <<snprintf>>. They differ only in allowing their caller to pass the
variable argument list as a <<va_list>> object (initialized by <<va_start>>)
rather than directly accepting a variable number of arguments.
<<vprintf>>, <<vfprintf>>, <<vasprintf>>, <<vsprintf>>, <<vsnprintf>>,
and <<vasnprintf>> are (respectively) variants of <<printf>>,
<<fprintf>>, <<asprintf>>, <<sprintf>>, <<snprintf>>, and
<<asnprintf>>. They differ only in allowing their caller to pass the
variable argument list as a <<va_list>> object (initialized by
<<va_start>>) rather than directly accepting a variable number of
arguments. The caller is responsible for calling <<va_end>>.
<<_vprintf_r>>, <<_vfprintf_r>>, <<_vasprintf_r>>, <<_vsprintf_r>>,
<<_vsnprintf_r>>, and <<_vasnprintf_r>> are reentrant versions of the
above.
RETURNS
The return values are consistent with the corresponding functions:
<<vasprintf>>/<<vsprintf>> returns the number of bytes in the output string,
save that the concluding <<NULL>> is not counted.
<<vprintf>> and <<vfprintf>> return the number of characters transmitted.
If an error occurs, <<vprintf>> and <<vfprintf>> return <<EOF>> and
<<vasprintf>> returns -1. No error returns occur for <<vsprintf>>.
The return values are consistent with the corresponding functions.
PORTABILITY
ANSI C requires all three functions.
ANSI C requires <<vprintf>>, <<vfprintf>>, <<vsprintf>>, and
<<vsnprintf>>. The remaining functions are newlib extensions.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.

DESCRIPTION
<<viprintf>>, <<vfiprintf>>, <<vasiprintf>>, <<vsiprintf>> and
<<vsniprintf>> are (respectively) variants of <<iprintf>>, <<fiprintf>>,
<<asiprintf>>, <<siprintf>>, and <<sniprintf>>. They differ only in
restricting the caller to use non-floating-point format specifiers.
<<viprintf>>, <<vfiprintf>>, <<vasiprintf>>, <<vsiprintf>>,
<<vsniprintf>>, and <<vasniprintf>> are (respectively) variants of
<<iprintf>>, <<fiprintf>>, <<asiprintf>>, <<siprintf>>, <<sniprintf>>,
and <<asniprintf>>. They differ only in allowing their caller to pass
the variable argument list as a <<va_list>> object (initialized by
<<va_start>>) rather than directly accepting a variable number of
arguments. The caller is responsible for calling <<va_end>>.
<<_viprintf_r>>, <<_vfiprintf_r>>, <<_vasiprintf_r>>,
<<_vsiprintf_r>>, <<_vsniprintf_r>>, and <<_vasniprintf_r>> are
reentrant versions of the above.
RETURNS
The return values are consistent with the corresponding functions:
<<vasiprintf>>/<<vsiprintf>> returns the number of bytes in the output string,
save that the concluding <<NULL>> is not counted.
<<viprintf>> and <<vfiprintf>> return the number of characters transmitted.
If an error occurs, <<viprintf>> and <<vfiprintf>> return <<EOF>> and
<<vasiprintf>> returns -1. No error returns occur for <<vsiprintf>>.
PORTABILITY
<<viprintf>>, <<vfiprintf>>, <<vasiprintf>>, <<vsiprintf>> and <<vsniprintf>>
are newlib extensions.
All of these functions are newlib extensions.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.

<<vsniprintf>> is a restricted version of <<vsnprintf>>: it has the same

formatting: the <<f>>, <<g>>, <<G>>, <<e>>, and <<F>> type specifiers
are not recognized.
RETURNS
<<vsniprintf>> returns the number of bytes in the output string,
save that the concluding <<NULL>> is not counted.
<<vsniprintf>> returns when the end of the format string is
encountered.
PORTABILITY
<<vsniprintf>> is not required by ANSI C.
