NAME
localeconv() - query the numeric formatting conventions of the current
locale
SYNOPSIS
#include <locale.h>
struct lconv *localeconv(void);
DESCRIPTION
localeconv() sets the components of an object of type struct lconv
(defined in <locale.h>) with values appropriate for the formatting of
numeric quantities (monetary and otherwise) according to the rules of
the program's current locale (see setlocale(3C)).
The members of the structure with type char * are strings, any of
which (except decimal_point) can point to "" (the empty string) to
indicate that the value is not available in the current locale or is
of zero length. The members with type char are non-negative numbers,
any of which can be CHAR_MAX (defined in <limits.h>) to indicate that
the value is not available in the current locale. The members include
the following:
char *decimal_point
The decimal point character used to format non-monetary
quantities. This is the same value as that returned by a
call to nl_langinfo() with RADIXCHAR as its argument (see
nl_langinfo(3C)).
char *thousands_sep
The character used to separate groups of digits to the left
of the decimal point character in formatted non-monetary
quantities. This is the same value as that returned by a
call to nl_langinfo() with THOUSEP as its argument (see
nl_langinfo(3C)).
char *grouping
A string where the numeric value of each byte indicates the
size of each group of digits in formatted non-monetary
quantities.
char *int_curr_symbol
The international currency symbol applicable to the current
locale. The first three characters contain the alphabetic
international currency symbol in accordance with those
specified in ISO 4217 Codes for the Representation of
Currency and Funds. The fourth character (immediately
preceding the null character) is the character used to
separate the international currency symbol from the monetary
quantity.

char *currency_symbol
The local currency symbol applicable to the current locale.
This value along with positioning information is returned by
a call to nl_langinfo() with CRNCYSTR as its argument (see
nl_langinfo(3C)).
char *mon_decimal_point
The decimal point used to format monetary quantities.
char *mon_thousands_sep
The separator for groups of digits to the left of the
decimal point in formatted monetary quantities.
char *mon_grouping
A string where the numeric value of each byte indicates the
size of each group of digits in formatted monetary
quantities.
char *positive_sign
The string used to indicate a non-negative-valued formatted
monetary quantity.
char *negative_sign
The string used to indicate a negative-valued formatted
monetary quantity.
char int_frac_digits
The number of fractional digits (those to the right of the
decimal point) to be displayed in an internationally
formatted monetary quantity.
char frac_digits
The number of fractional digits (those to the right of the
decimal point) to be displayed in a locally formatted
monetary quantity.
char p_cs_precedes
Set to 1 or 0 if the currency_symbol respectively precedes
or succeeds the value for a non-negative formatted monetary
quantity.
char p_sep_by_space
Set to 1 or 0 if the currency_symbol respectively is or is
not separated by a space from the value for a non-negative
formatted monetary quantity.
char n_cs_precedes
Set to 1 or 0 if the currency_symbol respectively precedes
or succeeds the value for a negative formatted monetary
quantity.

char n_sep_by_space
Set to 1 or 0 if the currency_symbol respectively is or is
not separated by a space from the value for a negative
formatted monetary quantity.
char p_sign_posn
Set to a value indicating the positioning of the
positive_sign for a non-negative formatted monetary
quantity.
char n_sign_posn
Set to a value indicating the positioning of the
negative_sign for a negative formatted monetary quantity.
The numeric value of each byte of grouping and mon_grouping is
interpreted according to the following:
CHAR_MAX No further grouping is to be performed.
0 The previous byte is to be repeatedly used for the
remainder of the digits.
other The value is the number of digits that comprise
the current group. The next byte is examined to
determine the size of the next group of digits to
the left of the current group.
The value of p_sign_posn and n_sign_posn is interpreted according to
the following:
0 Parentheses surround the quantity and currency_symbol.
1 The sign string precedes the quantity and currency_symbol.
2 The sign string succeeds the quantity and currency_symbol.
3 The sign string immediately precedes the currency_symbol.
4 The sign string immediately succeeds the currency_symbol.
localeconv() behaves as if no library function calls localeconv().
EXTERNAL INFLUENCES
Locale
The LC_NUMERIC category influences the decimal_point, thousands_sep,
and grouping members of the structure referenced by the pointer
returned from a call to localeconv().
The LC_MONETARY category influences all of the other members of this
structure.

International Code Set Support
Single- and multi-byte character code sets are supported.
RETURN VALUE
localeconv() returns a pointer to the filled-in struct lconv.
EXAMPLES
The following table illustrates the formatting used in five languages
for monetary quantities.
box, center; cb | cb | cb | cb lf4 | af4 | af4 | af4.
Country Positive format Negative format International format
= american $1,234.56 -$1,234.56 USD 1,234.56 _
italian L.1.234 -L.1.234 ITL.1.234 _
dutch F 1.234,56 F -1.234,56 NLG 1.234,56 _
norwegian kr1.234,56 kr1.234,56- NOK 1.234,56 _
portuguese 1,234$56 -1,234$56 PTE 1,234$56
For these five languages, the respective values for the monetary
members of the structure returned by localeconv() are:
box, center; cb | cb | cb | cb | cb | cb lf4 | cf4 | cf4 | cf4 | cf4 |
cf4. american italian dutch norwegian portuguese =

WARNINGS
The structure returned by localeconv() should not be modified by the
calling program. Calls to setlocale() with categories LC_ALL,
LC_MONETARY, or LC_NUMERIC can overwrite the contents of the structure
that localeconv() points to when it returns (see setlocale(3C)).
