+@section Accessing the Locale Information
 
-When you want to format a number or a currency amount using the
-conventions of the current locale, you can use the function
-@code{localeconv} to get the data on how to do it.  The function
-@code{localeconv} is declared in the header file @file{locale.h}.
+There are several ways to access the locale information.  The simplest
+way is to let the C library itself do the work.  Several of the
+functions in this library access implicitly the locale data and use
+what information is available in the currently selected locale.  This is
+how the locale model is meant to work normally.
+
+As an example take the @code{strftime} function which is meant to nicely
+format date and time information (@pxref{Formatting Date and Time}).
+Part of the standard information contained in the @code{LC_TIME}
+category are, e.g., the names of the months.  Instead of requiring the
+programmer to take care of providing the translations the
+@code{strftime} function does this all by itself.  When using @code{%A}
+in the format string this will be replaced by the appropriate weekday
+name of the locale currently selected for @code{LC_TIME}.  This is the
+easy part and wherever possible functions do things automatically as in
+this case.
+
+But there are quite often situations when there is simply no functions
+to perform the task or it is simply not possible to do the work
+automatically.  For these cases it is necessary to access the

+
+When writing the X/Open Portability Guide the authors realized that
+implicit used added to by the @code{localeconv} function is not enough
+to provide reasonable access to the locale information.  The
+information which was meant to be available in the locale (as later
+specified in the POSIX.1 standard) requires more possibilities to access
+it.  Therefore the @code{nl_langinfo} function was introduced.
+

+The @code{nl_langinfo} function can be used to access individual

+function which always returns all the information @code{nl_langinfo}

+fast and it is no problem to call this function multiple times.
+
+The second advantage is that not only the numeric and monetary
+formatting information is available.  Also the information of the
+@code{LC_TIME} and @code{LC_MESSAGES} categories is available.
+
+The type @code{nl_type} is defined in @file{nl_types.h}.
+The argument @var{item} is a numeric values which must be one of the

+
+The file @file{langinfo.h} defines a lot more symbols but none of them

+them in any situation.
+
+Please note that the return value for any valid argument can be used for
+in all situations (with the possible exception of the am/pm time format
+related values).  If the user has not selected any locale for the
+appropriate category @code{nl_langinfo} returns the information from the
+@code{"C"} locale.  It is therefore possible to use this function as
+shown in the example below.
+
+If the argument @var{item} is not valid the global variable @var{errno}
+is set to @code{EINVAL} and a @code{NULL} pointer is returned.
+@end deftypefun
+
+An example for the use of @code{nl_langinfo} is a function which has to
+print a given date and time in the locale specific way.  At first one
+might think the since @code{strftime} internally uses the locale
+information writing something like the following is enough:
+
+@smallexample
+size_t
+i18n_time_n_data (char *s, size_t len, const struct tm *tp)
+@{
+  return strftime (s, len, "%X %D", tp);
+@}
+@end smallexample
+
+The format contains no weekday or month names and therefore is
+internationally usable.  Wrong!  The output produced is something like
+@code{"hh:mm:ss MM/DD/YY"}.  This format is only recognizable in the
+USA.  Other countries use different formats.  Therefore the function
+should be rewritten like this:
+
+@smallexample
+size_t
+i18n_time_n_data (char *s, size_t len, const struct tm *tp)
+@{
+  return strftime (s, len, nl_langinfo (D_T_FMT), tp);
+@}
+@end smallexample
+
+Now the date and time format which is explicitly selected for the locale
+in place when the program runs is used.  If the user selects the locale
+correctly there should never be a misunderstanding over the time and
+date format.
+
+@node Formatting Numbers, , Locale Information, Locales
+@section A dedicated functions to format numbers
+
+We have seen the the structure returned by @code{localeconv} as well as
+the values given to @code{nl_langinfo} allow to retrieve the various
+pieces of locale specific information to format numbers and monetary
+amounts.  But we have also seen that the rules underlying this
+information are quite complex.
+
+Therefore the X/Open standards introduce a function which uses this
+information from the locale and so makes it is for the user to format
+numbers according to these rules.
+
+@deftypefun ssize_t strfmon (char *@var{s}, size_t @var{maxsize}, const char *@var{format}, @dots{})
+The @code{strfmon} function is similar to the @code{strftime} function
+in that it takes a description of a buffer (with size), a format string
+and values to write into a buffer a textual representation of the values
+according to the format string.  As for @code{strftime} the function
+also returns the number of bytes written into the buffer.
+
+There are two difference: @code{strfmon} can take more than one argument
+and of course the format specification is different.  The format string
+consists as for @code{strftime} of normal text which is simply printed
+and format specifiers, which here are also introduced using @samp{%}.
+Following the @samp{%} the function allows similar to @code{printf} a
+sequence of flags and other specifications before the format character:
+
+@itemize @bullet
+@item
+Immediately following the @samp{%} there can be one or more of the
+following flags:
+@table @asis
+@item @samp{=@var{f}}
+The single byte character @var{f} is used for this field as the numeric
+fill character.  By default this character is a space character.
+Filling with this character is only performed if a left precision
+is specified.  It is not just to fill to the given field width.
+@item @samp{^}
+The number is printed without grouping the digits using the rules of the
+current locale.  By default grouping is enabled.
+@item @samp{+}, @samp{(}
+At most one of these flags must be used.  They select which format to
+represent the sign of currency amount is used.  By default and if
+@samp{+} is used the locale equivalent to @math{+}/@math{-} is used.  If
+@samp{(} is used negative amounts are enclosed in parentheses.  The
+exact format is determined by the values of the @code{LC_MONETARY}
+category of the locale selected at program runtime.
+@item @samp{!}
+The output will not contain the currency symbol.
+@item @samp{-}
+The output will be formatted right-justified instead left-justified if
+the output does not fill the entire field width.
+@end table
+@end itemize
+
+The next part of a specification is an, again optional, specification of
+the field width.  The width is given by digits following the flags.  If
+no width is specified it is assumed to be @math{0}.  The width value is
+used after it is determined how much space the printed result needs.  If
+it does not require fewer characters than specified by the width value
+nothing happens.  Otherwise the output is extended to use as many
+characters as the width says by filling with spaces.  At which side
+depends on whether the @samp{-} flag was given or not.  If it was given,
+the spaces are added at the right, making the output right-justified and
+vice versa.
+
+So far the format looks familiar as it is similar to @code{printf} or
+@code{strftime} formats.  But the next two fields introduce something
+new.  The first one, if available, is introduced by a @samp{#} character
+which is followed by a decimal digit string.  The value of the digit
+string specifies the width the formatted digits left to the radix
+character.  This does @emph{not} include the grouping character needed
+if the @samp{^} flag is not given.  If the space needed to print the
+number does not fill the whole width the field is padded at the left
+side with the fill character which can be selected using the @samp{=}
+flag and which by default is a space.  For example, if the field width
+is selected as 6 and the number is @math{123}, the fill character is
+@samp{*} the result will be @samp{***123}.
+
+The next field is introduced by a @samp{.} (period) and consists of
+another decimal digit string.  Its value describes the number of
+characters printed after the radix character.  The default is
+selected from the current locale (@code{frac_digits},
+@code{int_frac_digits}, see @pxref{General Numeric}).  If the exact
+representation needs more digits than those specified by the field width
+the displayed value is rounded.  In case the number of fractional digits
+is selected to be zero, no radix character is printed.
+
+As a GNU extension the @code{strfmon} implementation in the GNU libc
+allows as the next field an optional @samp{L} as a format modifier.  If
+this modifier is given the argument is expected to be a @code{long
+double} instead of a @code{double} value.
+
+Finally as the last component of the format there must come a format
+specifying.  There are three specifiers defined:
+
+@table @asis
+@item @samp{i}
+The argument is formatted according to the locale's rules to format an
+international currency value.
+@item @samp{n}
+The argument is formatted according to the locale's rules to format an
+national currency value.
+@item @samp{%}
+Creates a @samp{%} in the output.  There must be no flag, width
+specifier or modifier given, only @samp{%%} is allowed.
+@end table
+
+As it is done for @code{printf}, the function read the format string
+from left to right and uses the value passed to the function following
+the format string.  The value are expected to be either of type
+@code{double} or @code{long double}, depending in the presence of the
+modifier @samp{L}.  The result is stored in the buffer pointed to by
+@var{s}.  At most @var{maxsize} characters are stored.
+
+The return value of the function is the number of characters stored in
+@var{s}, including the terminating NUL byte..  If the number of
+characters stored would exceed @var{maxsize} the function returns
+@math{-1} and the content of the buffer @var{s} is unspecified.  In this
+case @code{errno} is set to @code{E2BIG}.
+@end deftypefun
+
+A few examples should make the clear how to use this function.  It is
+assumed that all the following pieces of code are executed in a program
+which uses the locale valid for the USA (@code{en_US}).  The simplest
+form of the format is this:
+
+@smallexample
+strfmon (buf, 100, "@@%n@@%n@@%n@@", 123.45, -567.89, 12345.678);
+@end smallexample
+
+@noindent
+The output produced is
+@smallexample
+"@@$123.45@@-$123.45@@$12,345.68@@"
+@end smallexample
+
+We can notice several things here.  First, the width for all formats is
+different.  We have not specified a width in the format string and so
+this is no wonder.  Second, the third number is printed using thousands
+separators.  The thousands separator for the @code{en_US} locale is a
+comma.  Beside this the number is rounded.  The @math{.678} are rounded
+to @math{.68} since the format does not specify a precision and the
+default value in the locale is @math{2}.  A last thing is that the
+national currency symbol is printed since @samp{%n} was used, not
+@samp{i}.  The next example shows how we can align the output.
+
+@smallexample
+strfmon (buf, 100, "@@%=*11n@@%=*11n@@%=*11n@@", 123.45, -567.89, 12345.678);
+@end smallexample
+
+@noindent
+The output this time is:
+
+@smallexample
+"@@    $123.45@@   -$123.45@@ $12,345.68@@"
+@end smallexample
+
+Two things stand out.  First, all fields have the same width (eleven
+characters) since this is the width given in the format and since no
+number required more characters to be printed.  The second important
+point is that the fill character is not used.  This is correct since the
+white space was not used to fill the space specified by the right
+precision, but instead it is used to fill to the given width.  The
+difference becomes obvious if we now add a right width specification.
+
+@smallexample
+strfmon (buf, 100, "@@%=*11#5n@@%=*11#5n@@%=*11#5n@@",
+         123.45, -567.89, 12345.678);
+@end smallexample
+
+@noindent
+The output is
+
+@smallexample
+"@@ $***123.45@@-$***567.89@@ $12,456.68@@"
+@end smallexample
+
+Here we can see that all the currency symbols are now aligned and the
+space between the currency sign and the number is filled with the
+selected fill character.  Please note that although the right precision
+is selected to be @math{5} and @math{123.45} has three characters right
+of the radix character, the space is filled with three asterisks.  This
+is correct since as explained above, the right precision does not count
+the characters used for the thousands separators in.  One last example
+should explain the remaining functionality.
+
+@smallexample
+strfmon (buf, 100, "@@%=0(16#5.3i@@%=0(16#5.3i@@%=0(16#5.3i@@",
+         123.45, -567.89, 12345.678);
+@end smallexample
+
+@noindent
+This rather complex format string produces the following output:
+
+@smallexample
+"@@ USD 000123,450 @@(USD 000567.890)@@ USD 12,345.678 @@"
+@end smallexample
+
+The most noticeable change is the use of the alternative style to
+represent negative numbers.  In financial circles it is often done using
+braces and this is what the @samp{(} flag selected.  The fill character
+is now @samp{0}.  Please note that this @samp{0} character is not
+regarded as a numeric zero and therefore the first and second number are
+not printed using a thousands separator.  Since we use in the format the
+specifier @samp{i} instead of @samp{n} no the international form of the
+currency symbol is used.  This is a four letter string, in this case
+@code{"USD "}.  The last point is that since the left precision is
+selected to be three the first and second number are printed with and
+extra zero and the end and the third number is printed unrounded.
