LOCALECONV(3)          FreeBSD Library Functions Manual          LOCALECONV(3)

NAME
     localeconv -- natural language formatting for C

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <locale.h>

     struct lconv *
     localeconv(void);

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.

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.

SEE ALSO
     setlocale(3), strfmon(3)

     The localeconv() function first appeared in 4.4BSD.
