localeconv(3) BSD Library Functions Manual localeconv(3)
NAME
localeconv, localeconv_l -- natural language formatting for C
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <locale.h>
struct lconv *
localeconv(void);
#include <xlocale.h>
struct lconv *
localeconv_l(locale_t loc);
DESCRIPTION
The localeconv() function returns a pointer to a structure which provides
parameters for formatting numbers, especially currency values:
struct lconv {
char *decimal_point;
char *thousands_sep;
char *grouping;
char *int_curr_symbol;
char *currency_symbol;
char *mon_decimal_point;
char *mon_thousands_sep;
char *mon_grouping;
char *positive_sign;
char *negative_sign;
char int_frac_digits;
char frac_digits;
char p_cs_precedes;
char p_sep_by_space;
char n_cs_precedes;
char n_sep_by_space;
char p_sign_posn;
char n_sign_posn;
char int_p_cs_precedes;
char int_n_cs_precedes;
char int_p_sep_by_space;
char int_n_sep_by_space;
char int_p_sign_posn;
char int_n_sign_posn;
};
The individual fields have the following meanings:
decimal_point The decimal point character, except for currency val-
ues, cannot be an empty string.
thousands_sep The separator between groups of digits before the dec-
imal point, except for currency values.
grouping The sizes of the groups of digits, except for currency
values. This is a pointer to a vector of integers,
each of size char, representing group size from low
order digit groups to high order (right to left). The
list may be terminated with 0 or CHAR_MAX. If the
list is terminated with 0, the last group size before
the 0 is repeated to account for all the digits. If
the list is terminated with CHAR_MAX, no more grouping
is performed.
int_curr_symbol The standardized international currency symbol.
currency_symbol The local currency symbol.
mon_decimal_point The decimal point character for currency values.
mon_thousands_sep The separator for digit groups in currency values.
mon_grouping Like grouping but for currency values.
positive_sign The character used to denote nonnegative currency val-
ues, usually the empty string.
negative_sign The character used to denote negative currency values,
usually a minus sign.
int_frac_digits The number of digits after the decimal point in an
international-style currency value.
frac_digits The number of digits after the decimal point in the
local style for currency values.
p_cs_precedes 1 if the currency symbol precedes the currency value
for nonnegative values, 0 if it follows.
p_sep_by_space 1 if a space is inserted between the currency symbol
and the currency value for nonnegative values, 0 oth-
erwise.
n_cs_precedes Like p_cs_precedes but for negative values.
n_sep_by_space Like p_sep_by_space but for negative values.
p_sign_posn The location of the positive_sign with respect to a
nonnegative quantity and the currency_symbol, coded as
follows:
0 Parentheses around the entire string.
1 Before the string.
2 After the string.
3 Just before currency_symbol.
4 Just after currency_symbol.
n_sign_posn Like p_sign_posn but for negative currency values.
int_p_cs_precedes Same as p_cs_precedes, but for internationally format-
ted monetary quantities.
int_n_cs_precedes Same as n_cs_precedes, but for internationally format-
ted monetary quantities.
int_p_sep_by_space
Same as p_sep_by_space, but for internationally for-
matted monetary quantities.
int_n_sep_by_space
Same as n_sep_by_space, but for internationally for-
matted monetary quantities.
int_p_sign_posn Same as p_sign_posn, but for internationally formatted
monetary quantities.
int_n_sign_posn Same as n_sign_posn, but for internationally formatted
monetary quantities.
Unless mentioned above, an empty string as a value for a field indicates
a zero length result or a value that is not in the current locale. A
CHAR_MAX result similarly denotes an unavailable value.
While the localeconv() function uses the current locale, the
localeconv_l() function may be passed a locale directly. See xlocale(3)
for more information.
RETURN VALUES
The localeconv() function returns a pointer to a static object which may
be altered by later calls to setlocale(3) or localeconv().
ERRORS
No errors are defined.
