+DESCRIPTION
+Use <<fgetwc>> to get the next wide character from the file or stream
+identified by <[fp]>.  As a side effect, <<fgetwc>> advances the file's
+current position indicator.
+
+<<fgetwc_unlocked>> is a non-thread-safe version of <<fgetwc>>.
+<<fgetwc_unlocked>> may only safely be used within a scope
+protected by flockfile() (or ftrylockfile()) and funlockfile().  This
+function may safely be used in a multi-threaded program if and only
+if they are called while the invoking thread owns the (FILE *)
+object, as is the case after a successful call to the flockfile() or
+ftrylockfile() functions.  If threads are disabled, then
+<<fgetwc_unlocked>> is equivalent to <<fgetwc>>.
+
+The <<getwc>> and <<getwc_unlocked>> functions or macros functions identically
+to <<fgetwc>> and <<fgetwc_unlocked>>.  It may be implemented as a macro, and
+may evaluate its argument more than once. There is no reason ever to use it.
+
+<<_fgetwc_r>>, <<_getwc_r>>, <<_fgetwc_unlocked_r>>, and <<_getwc_unlocked_r>>
+are simply reentrant versions of the above functions that are passed the
+additional reentrant structure pointer argument: <[ptr]>.
+
+RETURNS
+The next wide character cast to <<wint_t>>, unless there is no more data,
+or the host system reports a read error; in either of these situations,
+<<fgetwc>> and <<getwc>> return <<WEOF>>.
+
+You can distinguish the two situations that cause an <<EOF>> result by
+using the <<ferror>> and <<feof>> functions.
+
+PORTABILITY
+<<fgetwc>> and <<getwc>> are required by C99 and POSIX.1-2001.
+
+<<fgetwc_unlocked>> and <<getwc_unlocked>> are GNU extensions.

+DESCRIPTION
+Reads at most <[n-1]> wide characters from <[fp]> until a newline
+is found. The wide characters including to the newline are stored
+in <[ws]>. The buffer is terminated with a 0.
+
+<<fgetws_unlocked>> is a non-thread-safe version of <<fgetws>>.
+<<fgetws_unlocked>> may only safely be used within a scope
+protected by flockfile() (or ftrylockfile()) and funlockfile().  This
+function may safely be used in a multi-threaded program if and only
+if they are called while the invoking thread owns the (FILE *)
+object, as is the case after a successful call to the flockfile() or
+ftrylockfile() functions.  If threads are disabled, then
+<<fgetws_unlocked>> is equivalent to <<fgetws>>.
+
+The <<_fgetws_r>> and <<_fgetws_unlocked_r>> functions are simply reentrant
+version of the above and are passed an additional reentrancy structure
+pointer: <[ptr]>.
+
+RETURNS
+<<fgetws>> returns the buffer passed to it, with the data
+filled in. If end of file occurs with some data already
+accumulated, the data is returned with no other indication. If
+no data are read, NULL is returned instead.
+
+PORTABILITY
+<<fgetws>> is required by C99 and POSIX.1-2001.
+
+<<fgetws_unlocked>> is a GNU extension.

+DESCRIPTION
+<<getwchar>> function or macro is the wide character equivalent of
+the <<getchar>> function.  You can use <<getwchar>> to get the next
+wide character from the standard input stream.  As a side effect,
+<<getwchar>> advances the standard input's current position indicator.
+
+<<getwchar_unlocked>> is a non-thread-safe version of <<getwchar>>.
+<<getwchar_unlocked>> may only safely be used within a scope
+protected by flockfile() (or ftrylockfile()) and funlockfile().  This
+function may safely be used in a multi-threaded program if and only
+if they are called while the invoking thread owns the (FILE *)
+object, as is the case after a successful call to the flockfile() or
+ftrylockfile() functions.  If threads are disabled, then
+<<getwchar_unlocked>> is equivalent to <<getwchar>>.
+
+The alternate functions <<_getwchar_r>> and <<_getwchar_unlocked_r>> are
+reentrant versions of the above.  The extra argument <[reent]> is a pointer to
+a reentrancy structure.
+
+RETURNS
+The next wide character cast to <<wint_t>>, unless there is no more
+data, or the host system reports a read error; in either of these
+situations, <<getwchar>> returns <<WEOF>>.
+
+You can distinguish the two situations that cause an <<WEOF>> result by
+using `<<ferror(stdin)>>' and `<<feof(stdin)>>'.
+
+PORTABILITY
+<<getwchar>> is required by C99.
+
+<<getwchar_unlocked>> is a GNU extension.

+	returns when it reaches the end of the format string.  If there are
+        more arguments than the format requires, excess arguments are
+        ignored.
+
+        <<fwprintf>> is like <<wprintf>>, except that output is directed
+        to the stream <[fd]> rather than <<stdout>>.
+
+        <<swprintf>> is like <<wprintf>>, except that output is directed
+        to the buffer <[str]> with a terminating wide <<NUL>>, and the
+	resulting string length is limited to at most <[size]> wide characters,
+	including the terminating <<NUL>>.  It is considered an error if the
+	output (including the terminating wide-<<NULL>>) does not fit into
+	<[size]> wide characters.  (This error behavior is not the same as for
+	<<snprintf>>, which <<swprintf>> is otherwise completely analogous to.
+	While <<snprintf>> allows the needed size to be known simply by giving
+	<[size]>=0, <<swprintf>> does not, giving an error instead.)
+
+        For <<swprintf>> 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 wide 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.
+	This positional parameters method is a POSIX extension to the C
+	standard definition for the functions.
+
+	o <[flags]>
+
+	<[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 '
+			A POSIX extension to the C standard.  However, this
+			implementation presently treats it as a no-op, which
+			is the default behavior for the C locale, anyway.  (If
+			it did what it is supposed to, when <[type]> were <<i>>,
+			<<d>>, <<u>>, <<f>>, <<F>>, <<g>>, or <<G>>, the
+			integer portion of the conversion would be formatted
+			with thousands' grouping wide characters.)
+
+		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.
+
+	        o +
+			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.
+
+	        o 0
+			If the <[type]> character is <<d>>, <<i>>,
+			<<o>>, <<u>>, <<x>>, <<X>>, <<a>>, <<A>>,
+			<<e>>, <<E>>, <<f>>, <<F>>, <<g>>, or <<G>>:  leading
+			zeros 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.
+
+			Note that <<0>> is interpreted as a flag, not
+		        as the beginning of a field width.
+
+	        o #
+			The result is to be converted to an
+			alternative form, according to the <[type]>
+			character.
+		o-
+
+	The alternative form output with the # flag depends on the <[type]>
+	character:
+
+		o+
+		o o
+			Increases precision to force the first
+			digit of the result to be a zero.
+
+		o x
+			A non-zero result will have a <<0x>>
+			prefix.
+
+		o X
+			A non-zero result will have a <<0X>>
+			prefix.
+
+		o a, A, e, E, f, or F
+			The result will always contain a
+			decimal point even if no digits follow
+			the point.  (Normally, a decimal point
+			appears only if a digit follows it.)
+			Trailing zeros are removed.
+
+		o g or G
+			The result will always contain a
+			decimal point even if no digits follow
+			the point.  Trailing zeros are not
+			removed.
+
+		o all others
+			Undefined.
+
+		o-
+
+
+	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.  If positional arguments are used, then the
+		width must also be specified positionally as <<*m$>>,
+		with m as a decimal integer.  Negative field widths
+		are treated as specifying the minus (<<->>) flag for
+		left justfication, along with a positive field width.
+		The resulting format may be wider than the specified
+		width.
+
+	o <[prec]>
+
+		<[prec]> is an optional field; if present, it is
+		introduced with `<<.>>' (a period). You can specify
+		the precision either directly as a decimal integer or
+		indirectly by using an asterisk (<<*>>), in which case
+		an <<int>> argument is used as the precision.  If
+		positional arguments are used, then the precision must
+		also be specified positionally as <<*m$>>, 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]>
+
+		<[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 hh
+			With <<d>>, <<i>>, <<o>>, <<u>>, <<x>>, or

+
+		o ll
+			With <<d>>, <<i>>, <<o>>, <<u>>, <<x>>, or
+			<<X>>, specifies that the argument is a

+
+			With <<n>>, specifies that the argument is a

+			With <<d>>, <<i>>, <<o>>, <<u>>, <<x>>, or

+
+		o-
+
+	o   <[type]>
+
+		<[type]> specifies what kind of conversion <<wprintf>>
+		performs.  Here is a table of these:
+
+		o+
+		o %
+			Prints the percent character (<<%>>).
+
+		o c
+			If no <<l>> qualifier is present, the int argument shall
+			be converted to a wide character as if by calling
+			the btowc() function and the resulting wide character
+			shall be written.  Otherwise, the wint_t argument
+			shall be converted to wchar_t, and written.
+
+		o C
+			Short for <<%lc>>.  A POSIX extension to the C standard.
+
+		o s
+			If no <<l>> qualifier is present, the application
+			shall ensure that the argument is a pointer to a
+			character array containing a character sequence
+			beginning in the initial shift state.  Characters
+			from the array shall be converted as if by repeated
+			calls to the mbrtowc() function, with the conversion
+			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 shall be
+			written.  If the precision is not specified, or is
+			greater than the size of the array, the application
+			shall ensure that the array contains a null wide
+			character.
+
+			If an <<l>> qualifier is present, the application
+			shall ensure that the argument is a pointer to an
+			array of type wchar_t. Wide characters from the array
+			shall be 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 application shall ensure that the array contains
+			a null wide character. If a precision is specified,
+			no more than that many wide characters shall be
+			written.
+
+		o S
+			Short for <<%ls>>.  A POSIX extension to the C standard.
+
+		o d or i
+			Prints a signed decimal integer; takes an
+			<<int>>.  Leading zeros are inserted as
+			necessary to reach the precision.  A value of 0 with
+			a precision of 0 produces an empty string.
+
+		o o
+			Prints an unsigned octal integer; takes an
+			<<unsigned>>.  Leading zeros are inserted as
+			necessary to reach the precision.  A value of 0 with
+			a precision of 0 produces an empty string.
+
+		o u
+			Prints an unsigned decimal integer; takes an
+			<<unsigned>>.  Leading zeros are inserted as
+			necessary to reach the precision.  A value of 0 with
+			a precision of 0 produces an empty string.
+
+		o x
+			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 value of 0 with
+			a precision of 0 produces an empty string.
+
+		o X
+			Like <<x>>, but uses <<ABCDEF>> as digits
+			beyond <<9>>.
+
+		o f
+			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 <<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
+			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 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
+			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
+			Takes a pointer to <<int>>, and stores a count
+			of the number of bytes written so far.  No
+			output is created.
+
+		o p
+			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 m
+			Prints the output of <<strerror(errno)>>; no
+			argument is required.  A GNU extension.
+
+		o-
+	O-
+
+        <<_wprintf_r>>, <<_fwprintf_r>>, <<_swprintf_r>>, are simply
+        reentrant versions of the functions above.
+
+RETURNS
+On success, <<swprintf>> return the number of wide characters in
+the output string, except the concluding <<NUL>> is not counted.
+<<wprintf>> and <<fwprintf>> return the number of characters transmitted.
+
+If an error occurs, the result of <<wprintf>>, <<fwprintf>>, and
+<<swprintf>> is a negative value.  For <<wprintf>> and <<fwprintf>>,
+<<errno>> may be set according to <<fputwc>>.  For <<swprintf>>, <<errno>>
+may be set to EOVERFLOW if <[size]> is greater than INT_MAX / sizeof (wchar_t),
+or when the output does not fit into <[size]> wide characters (including the
+terminating wide <<NULL>>).
+
+BUGS
+The ``''' (quote) flag does not work when locale's thousands_sep is not empty.
+
+PORTABILITY
+POSIX-1.2008 with extensions; C99 (compliant except for POSIX extensions).
+
+Depending on how newlib was configured, not all format specifiers are
+supported.
+
+Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
+<<lseek>>, <<read>>, <<sbrk>>, <<write>>.

+DESCRIPTION
+        <<wscanf>> scans a series of input fields from standard input,
+		one wide character at a time.  Each field is interpreted according to
+		a format specifier passed to <<wscanf>> in the format string at
+        <<*<[format]>>>.  <<wscanf>> stores the interpreted input from
+		each field at the address passed to it as the corresponding argument
+		following <[format]>.  You must supply the same number of
+		format specifiers and address arguments as there are input fields.
+
+        There must be sufficient address arguments for the given format
+        specifiers; if not the results are unpredictable and likely
+        disasterous.  Excess address arguments are merely ignored.
+
+        <<wscanf>> often produces unexpected results if the input diverges from
+        an expected pattern. Since the combination of <<gets>> or <<fgets>>
+        followed by <<swscanf>> is safe and easy, that is the preferred way
+        to be certain that a program is synchronized with input at the end
+		of a line.
+
+        <<fwscanf>> and <<swscanf>> are identical to <<wscanf>>, other than the
+        source of input: <<fwscanf>> reads from a file, and <<swscanf>>
+		from a string.
+
+        The routines <<_wscanf_r>>, <<_fwscanf_r>>, and <<_swscanf_r>> are reentrant
+        versions of <<wscanf>>, <<fwscanf>>, and <<swscanf>> that take an additional
+        first argument pointing to a reentrancy structure.
+
+        The string at <<*<[format]>>> is a wide character sequence composed
+        of zero or more directives. Directives are composed of
+        one or more whitespace characters, non-whitespace characters,
+        and format specifications.
+
+        Whitespace characters are blank (<< >>), tab (<<\t>>), or
+		newline (<<\n>>).
+        When <<wscanf>> encounters a whitespace character in the format string
+        it will read (but not store) all consecutive whitespace characters
+        up to the next non-whitespace character in the input.
+
+        Non-whitespace characters are all other ASCII characters except the
+        percent sign (<<%>>).  When <<wscanf>> encounters a non-whitespace
+        character in the format string it will read, but not store
+        a matching non-whitespace character.
+
+        Format specifications tell <<wscanf>> to read and convert characters
+        from the input field into specific types of values, and store then
+        in the locations specified by the address arguments.
+
+        Trailing whitespace is left unread unless explicitly
+        matched in the format string.
+
+        The format specifiers must begin with a percent sign (<<%>>)
+        and have the following form:
+
+.       %[*][<[width]>][<[size]>]<[type]>
+
+        Each format specification begins with the percent character (<<%>>).
+        The other fields are:
+	O+
+		o *
+
+		an optional marker; if present, it suppresses interpretation and
+        assignment of this input field.
+
+        o <[width]>
+
+		an optional maximum field width: a decimal integer,
+		which controls the maximum number of characters that
+		will be read before converting the current input field.  If the
+		input field has fewer than <[width]> characters, <<wscanf>>
+		reads all the characters in the field, and then
+		proceeds with the next field and its format specification.
+
+		If a whitespace or a non-convertable wide character occurs
+		before <[width]> character are read, the characters up
+		to that character are read, converted, and stored.
+		Then <<wscanf>> proceeds to the next format specification.
+
+        o <[size]>
+
+		<<h>>, <<j>>, <<l>>, <<L>>, <<t>>, and <<z>> are optional size
+		characters which override the default way that <<wscanf>>
+		interprets the data type of the corresponding argument.

+
+		A character to specify what kind of conversion

+                characters:
+
+		o+
+		o %
+		No conversion is done; the percent character (<<%>>) is stored.
+
+		o c
+		Scans one wide character.  Corresponding <[arg]>: <<(char *arg)>>.
+		Otherwise, if an <<l>> specifier is present, the corresponding
+		<[arg]> is a <<(wchar_t *arg)>>.
+
+		o s
+		Reads a character string into the array supplied.
+		Corresponding <[arg]>: <<(char arg[])>>.
+		If an <<l>> specifier is present, the corresponding <[arg]> is a <<(wchar_t *arg)>>.
+
+		o [<[pattern]>]
+		Reads a non-empty character string into memory
+		starting at <[arg]>.  This area must be large
+		enough to accept the sequence and a
+		terminating null character which will be added
+		automatically.  (<[pattern]> is discussed in the paragraph following
+		this table).  Corresponding <[arg]>: <<(char *arg)>>.
+		If an <<l>> specifier is present, the corresponding <[arg]> is
+		a <<(wchar_t *arg)>>.
+
+		o d
+		Reads a decimal integer into the corresponding <[arg]>: <<(int *arg)>>.
+
+		o o
+		Reads an octal integer into the corresponding <[arg]>: <<(int *arg)>>.
+
+		o u
+		Reads an unsigned decimal integer into the corresponding
+		<[arg]>: <<(unsigned int *arg)>>.
+
+		o x,X
+		Read a hexadecimal integer into the corresponding <[arg]>:
+		<<(int *arg)>>.
+
+		o e, f, g
+		Read a floating-point number into the corresponding <[arg]>:
+		<<(float *arg)>>.
+
+		o E, F, G
+		Read a floating-point number into the corresponding <[arg]>:
+		<<(double *arg)>>.
+
+		o i
+		Reads a decimal, octal or hexadecimal integer into the
+		corresponding <[arg]>: <<(int *arg)>>.
+
+		o n
+		Stores the number of characters read in the corresponding
+		<[arg]>: <<(int *arg)>>.
+
+		o p
+                Stores a scanned pointer.  ANSI C leaves the details
+		to each implementation; this implementation treats
+		<<%p>> exactly the same as <<%U>>.  Corresponding
+		<[arg]>: <<(void **arg)>>.
+                o-
+
+	A <[pattern]> of characters surrounded by square brackets can be used
+	instead of the <<s>> type character.  <[pattern]> is a set of
+	characters which define a search set of possible characters making up
+	the <<wscanf>> input field.  If the first character in the brackets is a
+	caret (<<^>>), the search set is inverted to include all ASCII characters
+	except those between the brackets.  There is no range facility as is
+	defined in the corresponding non-wide character scanf functions.
+	Ranges are not part of the POSIX standard.
+
+	Here are some <[pattern]> examples:
+		o+
+		o %[abcd]
+		matches wide character strings containing only
+		<<a>>, <<b>>, <<c>>, and <<d>>.
+
+		o %[^abcd]
+		matches wide character strings containing any characters except
+		<<a>>, <<b>>, <<c>>, or <<d>>.
+
+		o %[A-DW-Z]
+		Note: No wide character ranges, so this expression matches wide
+		character strings containing <<A>>, <<->>, <<D>>, <<W>>, <<Z>>.
+		o-
+
+	Floating point numbers (for field types <<e>>, <<f>>, <<g>>, <<E>>,
+	<<F>>, <<G>>) must correspond to the following general form:
+
+.		[+/-] ddddd[.]ddd [E|e[+|-]ddd]
+
+	where objects inclosed in square brackets are optional, and <<ddd>>
+	represents decimal, octal, or hexadecimal digits.
+	O-
+
+RETURNS
+        <<wscanf>> returns the number of input fields successfully
+        scanned, converted and stored; the return value does
+        not include scanned fields which were not stored.
+
+        If <<wscanf>> attempts to read at end-of-file, the return
+        value is <<EOF>>.
+
+        If no fields were stored, the return value is <<0>>.
+
+        <<wscanf>> might stop scanning a particular field before
+        reaching the normal field end character, or may
+        terminate entirely.
+
+        <<wscanf>> stops scanning and storing the current field
+        and moves to the next input field (if any)
+        in any of the following situations:
+
+	O+
+	o       The assignment suppressing character (<<*>>) appears
+	after the <<%>> in the format specification; the current
+	input field is scanned but not stored.
+
+	o       <[width]> characters have been read (<[width]> is a
+	width specification, a positive decimal integer).
+
+	o       The next wide character read cannot be converted
+	under the the current format (for example,
+	if a <<Z>> is read when the format is decimal).
+
+	o       The next wide character in the input field does not appear
+	in the search set (or does appear in the inverted search set).
+	O-
+
+	When <<wscanf>> stops scanning the current input field for one of
+	these reasons, the next character is considered unread and
+	used as the first character of the following input field, or the
+	first character in a subsequent read operation on the input.
+
+	<<wscanf>> will terminate under the following circumstances:
+
+	O+
+	o       The next wide character in the input field conflicts
+	with a corresponding non-whitespace character in the
+	format string.
+
+	o       The next wide character in the input field is <<WEOF>>.
+
+	o       The format string has been exhausted.
+	O-
+
+	When the format string contains a wide character sequence that is
+	not part of a format specification, the same wide character
+	sequence must appear in the input; <<wscanf>> will
+	scan but not store the matched characters.  If a
+	conflict occurs, the first conflicting wide character remains in the
+	input as if it had never been read.
+
+PORTABILITY
+<<wscanf>> is C99, POSIX-1.2008.
+
+Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
+<<lseek>>, <<read>>, <<sbrk>>, <<write>>.

+
+DESCRIPTION
+<<ungetwc>> is used to return wide characters back to <[stream]> to be
+read again.  If <[wc]> is WEOF, the stream is unchanged.  Otherwise, the
+wide character <[wc]> is put back on the stream, and subsequent reads will see
+the wide chars pushed back in reverse order.  Pushed wide chars are lost if the
+stream is repositioned, such as by <<fseek>>, <<fsetpos>>, or
+<<rewind>>.
+
+The underlying file is not changed, but it is possible to push back
+something different than what was originally read.  Ungetting a
+character will clear the end-of-stream marker, and decrement the file
+position indicator.  Pushing back beyond the beginning of a file gives
+unspecified behavior.
+
+The alternate function <<_ungetwc_r>> is a reentrant version.  The
+extra argument <[reent]> is a pointer to a reentrancy structure.
+
+RETURNS
+The wide character pushed back, or <<WEOF>> on error.

+DESCRIPTION
+The <<mbsrtowcs>> function converts a sequence of multibyte characters
+pointed to indirectly by <[src]> into a sequence of corresponding wide
+characters and stores at most <[len]> of them in the wchar_t array pointed
+to by <[dst]>, until it encounters a terminating null character ('\0').
+
+If <[dst]> is NULL, no characters are stored.
+
+If <[dst]> is not NULL, the pointer pointed to by <[src]> is updated to point
+to the character after the one that conversion stopped at.  If conversion
+stops because a null character is encountered, *<[src]> is set to NULL.
+
+The mbstate_t argument, <[ps]>, is used to keep track of the shift state.  If
+it is NULL, <<mbsrtowcs>> uses an internal, static mbstate_t object, which
+is initialized to the initial conversion state at program startup.
+
+The <<mbsnrtowcs>> function behaves identically to <<mbsrtowcs>>, except that
+conversion stops after reading at most <[nms]> bytes from the buffer pointed
+to by <[src]>.
+
+RETURNS
+The <<mbsrtowcs>> and <<mbsnrtowcs>> functions return the number of wide
+characters stored in the array pointed to by <[dst]> if successful, otherwise
+it returns (size_t)-1.

+When _MB_CAPABLE is not defined, this is a minimal ANSI-conforming

+and they are ``converted'' to wide-char versions simply by byte
+extension.

+the conversion, passing a state variable to allow state dependent
+decoding.  The result is based on the locale setting which may

+
+RETURNS
+This implementation of <<mbstowcs>> returns <<0>> if
+<[s]> is <<NULL>> or is the empty string; 
+it returns <<-1>> if _MB_CAPABLE and one of the
+multi-byte characters is invalid or incomplete;
+otherwise it returns the minimum of: <<n>> or the
+number of multi-byte characters in <<s>> plus 1 (to
+compensate for the nul character).
+If the return value is -1, the state of the <<pwc>> string is
+indeterminate.  If the input has a length of 0, the output
+string will be modified to contain a wchar_t nul terminator.

+
+
+DESCRIPTION
+<<random>> returns a different integer each time it is called; each
+integer is chosen by an algorithm designed to be unpredictable, so
+that you can use <<random>> when you require a random number.
+The algorithm depends on a static variable called the ``random seed'';
+starting with a given value of the random seed always produces the
+same sequence of numbers in successive calls to <<random>>.
+
+You can set the random seed using <<srandom>>; it does nothing beyond
+storing its argument in the static variable used by <<rand>>.  You can
+exploit this to make the pseudo-random sequence less predictable, if
+you wish, by using some other unpredictable value (often the least
+significant parts of a time-varying value) as the random seed before
+beginning a sequence of calls to <<rand>>; or, if you wish to ensure
+(for example, while debugging) that successive runs of your program
+use the same ``random'' numbers, you can use <<srandom>> to set the same
+random seed at the outset.
+
+RETURNS
+<<random>> returns the next pseudo-random integer in sequence; it is a
+number between <<0>> and <<RAND_MAX>> (inclusive).
+
+<<srandom>> does not return a result.
+
+NOTES
+<<random>> and <<srandom>> are unsafe for multi-threaded applications.
+
+_XOPEN_SOURCE may be any value >= 500.
+
+PORTABILITY

+DESCRIPTION
+The <<wcsrtombs>> function converts a string of wide characters indirectly
+pointed to by <[src]> to a corresponding multibyte character string stored in
+the array pointed to by <[dst]>.  No more than <[len]> bytes are written to
+<[dst]>.
+
+If <[dst]> is NULL, no characters are stored.
+
+If <[dst]> is not NULL, the pointer pointed to by <[src]> is updated to point
+to the character after the one that conversion stopped at.  If conversion
+stops because a null character is encountered, *<[src]> is set to NULL.
+
+The mbstate_t argument, <[ps]>, is used to keep track of the shift state.  If
+it is NULL, <<wcsrtombs>> uses an internal, static mbstate_t object, which
+is initialized to the initial conversion state at program startup.
+
+The <<wcsnrtombs>> function behaves identically to <<wcsrtombs>>, except that
+conversion stops after reading at most <[nwc]> characters from the buffer
+pointed to by <[src]>.
+
+RETURNS
+The <<wcsrtombs>> and <<wcsnrtombs>> functions return the number of bytes
+stored in the array pointed to by <[dst]> (not including any terminating
+null), if successful, otherwise it returns (size_t)-1.
+

+
+DESCRIPTION
+	The function <<wcstod>> parses the wide character string <[str]>,
+	producing a substring which can be converted to a double
+	value.  The substring converted is the longest initial
+	subsequence of <[str]>, beginning with the first
+	non-whitespace character, that has one of these formats:
+	.[+|-]<[digits]>[.[<[digits]>]][(e|E)[+|-]<[digits]>]
+	.[+|-].<[digits]>[(e|E)[+|-]<[digits]>]
+	.[+|-](i|I)(n|N)(f|F)[(i|I)(n|N)(i|I)(t|T)(y|Y)]
+	.[+|-](n|N)(a|A)(n|N)[<(>[<[hexdigits]>]<)>]
+	.[+|-]0(x|X)<[hexdigits]>[.[<[hexdigits]>]][(p|P)[+|-]<[digits]>]
+	.[+|-]0(x|X).<[hexdigits]>[(p|P)[+|-]<[digits]>]
+	The substring contains no characters if <[str]> is empty, consists
+	entirely of whitespace, or if the first non-whitespace
+	character is something other than <<+>>, <<->>, <<.>>, or a
+	digit, and cannot be parsed as infinity or NaN. If the platform
+	does not support NaN, then NaN is treated as an empty substring.
+	If the substring is empty, no conversion is done, and
+	the value of <[str]> is stored in <<*<[tail]>>>.  Otherwise,
+	the substring is converted, and a pointer to the final string
+	(which will contain at least the terminating null character of
+	<[str]>) is stored in <<*<[tail]>>>.  If you want no
+	assignment to <<*<[tail]>>>, pass a null pointer as <[tail]>.
+	<<wcstof>> is identical to <<wcstod>> except for its return type.
+
+	This implementation returns the nearest machine number to the
+	input decimal string.  Ties are broken by using the IEEE
+	round-even rule.  However, <<wcstof>> is currently subject to
+	double rounding errors.
+
+	The alternate functions <<_wcstod_r>> and <<_wcstof_r>> are 
+	reentrant versions of <<wcstod>> and <<wcstof>>, respectively.
+	The extra argument <[reent]> is a pointer to a reentrancy structure.
+
+RETURNS
+	Return the converted substring value, if any.  If
+	no conversion could be performed, 0 is returned.  If the
+	correct value is out of the range of representable values,
+	plus or minus <<HUGE_VAL>> is returned, and <<ERANGE>> is
+	stored in errno. If the correct value would cause underflow, 0
+	is returned and <<ERANGE>> is stored in errno.
+
+Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
+<<lseek>>, <<read>>, <<sbrk>>, <<write>>.

+
+DESCRIPTION
+The function <<wcstol>> converts the wide string <<*<[s]>>> to
+a <<long>>. First, it breaks down the string into three parts:
+leading whitespace, which is ignored; a subject string consisting
+of characters resembling an integer in the radix specified by <[base]>;
+and a trailing portion consisting of zero or more unparseable characters,
+and always including the terminating null character. Then, it attempts
+to convert the subject string into a <<long>> and returns the
+result.
+
+If the value of <[base]> is 0, the subject string is expected to look
+like a normal C integer constant: an optional sign, a possible `<<0x>>'
+indicating a hexadecimal base, and a number. If <[base]> is between
+2 and 36, the expected form of the subject is a sequence of letters
+and digits representing an integer in the radix specified by <[base]>,
+with an optional plus or minus sign. The letters <<a>>--<<z>> (or,
+equivalently, <<A>>--<<Z>>) are used to signify values from 10 to 35;
+only letters whose ascribed values are less than <[base]> are
+permitted. If <[base]> is 16, a leading <<0x>> is permitted.
+
+The subject sequence is the longest initial sequence of the input
+string that has the expected form, starting with the first
+non-whitespace character.  If the string is empty or consists entirely
+of whitespace, or if the first non-whitespace character is not a
+permissible letter or digit, the subject string is empty.
+
+If the subject string is acceptable, and the value of <[base]> is zero,
+<<wcstol>> attempts to determine the radix from the input string. A
+string with a leading <<0x>> is treated as a hexadecimal value; a string with
+a leading 0 and no <<x>> is treated as octal; all other strings are
+treated as decimal. If <[base]> is between 2 and 36, it is used as the
+conversion radix, as described above. If the subject string begins with
+a minus sign, the value is negated. Finally, a pointer to the first
+character past the converted subject string is stored in <[ptr]>, if
+<[ptr]> is not <<NULL>>.
+
+If the subject string is empty (or not in acceptable form), no conversion
+is performed and the value of <[s]> is stored in <[ptr]> (if <[ptr]> is
+not <<NULL>>).
+
+The alternate function <<_wcstol_r>> is a reentrant version.  The
+extra argument <[reent]> is a pointer to a reentrancy structure.
+
+RETURNS
+<<wcstol>> returns the converted value, if any. If no conversion was
+made, 0 is returned.
+
+<<wcstol>> returns <<LONG_MAX>> or <<LONG_MIN>> if the magnitude of
+the converted value is too large, and sets <<errno>> to <<ERANGE>>.
+
+PORTABILITY
+<<wcstol>> is ANSI.
+
+No supporting OS subroutines are required.

+
+DESCRIPTION
+When _MB_CAPABLE is not defined, this is a minimal ANSI-conforming 
+implementation of <<wcstombs>>.  In this case,
+all wide-characters are expected to represent single bytes and so
+are converted simply by casting to char.
+
+When _MB_CAPABLE is defined, this routine calls <<_wcstombs_r>> to perform
+the conversion, passing a state variable to allow state dependent
+decoding.  The result is based on the locale setting which may
+be restricted to a defined set of locales.
+
+RETURNS
+This implementation of <<wcstombs>> returns <<0>> if
+<[s]> is <<NULL>> or is the empty string; 
+it returns <<-1>> if _MB_CAPABLE and one of the
+wide-char characters does not represent a valid multi-byte character;
+otherwise it returns the minimum of: <<n>> or the
+number of bytes that are transferred to <<s>>, not including the
+nul terminator.
+
+If the return value is -1, the state of the <<pwc>> string is
+indeterminate.  If the input has a length of 0, the output
+string will be modified to contain a wchar_t nul terminator if
+<<n>> > 0.
+
+PORTABILITY
+<<wcstombs>> is required in the ANSI C standard.  However, the precise
+effects vary with the locale.
+
+<<wcstombs>> requires no supporting OS subroutines.

+
+DESCRIPTION
+The function <<wcstoul>> converts the wide string <<*<[s]>>> to
+an <<unsigned long>>. First, it breaks down the string into three parts:
+leading whitespace, which is ignored; a subject string consisting
+of the digits meaningful in the radix specified by <[base]>
+(for example, <<0>> through <<7>> if the value of <[base]> is 8);
+and a trailing portion consisting of one or more unparseable characters,
+which always includes the terminating null character. Then, it attempts
+to convert the subject string into an unsigned long integer, and returns the
+result.
+
+If the value of <[base]> is zero, the subject string is expected to look
+like a normal C integer constant (save that no optional sign is permitted):
+a possible <<0x>> indicating hexadecimal radix, and a number.
+If <[base]> is between 2 and 36, the expected form of the subject is a
+sequence of digits (which may include letters, depending on the
+base) representing an integer in the radix specified by <[base]>.
+The letters <<a>>--<<z>> (or <<A>>--<<Z>>) are used as digits valued from
+10 to 35. If <[base]> is 16, a leading <<0x>> is permitted.
+
+The subject sequence is the longest initial sequence of the input
+string that has the expected form, starting with the first
+non-whitespace character.  If the string is empty or consists entirely
+of whitespace, or if the first non-whitespace character is not a
+permissible digit, the subject string is empty.
+
+If the subject string is acceptable, and the value of <[base]> is zero,
+<<wcstoul>> attempts to determine the radix from the input string. A
+string with a leading <<0x>> is treated as a hexadecimal value; a string with
+a leading <<0>> and no <<x>> is treated as octal; all other strings are
+treated as decimal. If <[base]> is between 2 and 36, it is used as the
+conversion radix, as described above. Finally, a pointer to the first
+character past the converted subject string is stored in <[ptr]>, if
+<[ptr]> is not <<NULL>>.
+
+If the subject string is empty (that is, if <<*>><[s]> does not start
+with a substring in acceptable form), no conversion
+is performed and the value of <[s]> is stored in <[ptr]> (if <[ptr]> is
+not <<NULL>>).
+
+The alternate function <<_wcstoul_r>> is a reentrant version.  The
+extra argument <[reent]> is a pointer to a reentrancy structure.
+
+
+RETURNS
+<<wcstoul>> returns the converted value, if any. If no conversion was
+made, <<0>> is returned.
+
+<<wcstoul>> returns <<ULONG_MAX>> if the magnitude of the converted
+value is too large, and sets <<errno>> to <<ERANGE>>.
+
+PORTABILITY
+<<wcstoul>> is ANSI.
+
+<<wcstoul>> requires no supporting OS subroutines.

+FUNCTION
+<<wctomb>>---minimal wide char to multibyte converter
+
+INDEX
+	wctomb
+
+ANSI_SYNOPSIS
+	#include <stdlib.h>
+	int wctomb(char *<[s]>, wchar_t <[wchar]>);
+
+TRAD_SYNOPSIS
+	#include <stdlib.h>
+	int wctomb(<[s]>, <[wchar]>)
+	char *<[s]>;
+	wchar_t <[wchar]>;
+
+DESCRIPTION
+When _MB_CAPABLE is not defined, this is a minimal ANSI-conforming 
+implementation of <<wctomb>>.  The
+only ``wide characters'' recognized are single bytes,
+and they are ``converted'' to themselves.  
+
+When _MB_CAPABLE is defined, this routine calls <<_wctomb_r>> to perform
+the conversion, passing a state variable to allow state dependent
+decoding.  The result is based on the locale setting which may
+be restricted to a defined set of locales.
+
+Each call to <<wctomb>> modifies <<*<[s]>>> unless <[s]> is a null
+pointer or _MB_CAPABLE is defined and <[wchar]> is invalid.
+
+RETURNS
+This implementation of <<wctomb>> returns <<0>> if
+<[s]> is <<NULL>>; it returns <<-1>> if _MB_CAPABLE is enabled
+and the wchar is not a valid multi-byte character, it returns <<1>>
+if _MB_CAPABLE is not defined or the wchar is in reality a single
+byte character, otherwise it returns the number of bytes in the
+multi-byte character.
+
+PORTABILITY
+<<wctomb>> is required in the ANSI C standard.  However, the precise
+effects vary with the locale.
+
+<<wctomb>> requires no supporting OS subroutines.
