LOCALECONV(3)						   BSD 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);

     #include <xlocale.h>

     struct lconv *
     localeconv_l(locale_t locale);

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 values, cannot be an empty string.

     thousands_sep	The separator between groups of digits before the decimal 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 dig-
			its.  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 values, 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 otherwise.

     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 formatted monetary quantities.

     int_n_cs_precedes	Same as n_cs_precedes, but for internationally formatted monetary quantities.

     int_p_sep_by_space
			Same as p_sep_by_space, but for internationally formatted monetary quantities.

     int_n_sep_by_space
			Same as n_sep_by_space, but for internationally formatted 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.

     The localeconv_l() function takes an explicit locale parameter.  For more information, see xlocale(3).

RETURN VALUES

     The localeconv() function returns a pointer to a static object which may be altered by later calls to setlocale(3) or localeconv().  The
     return value for localeconv_l() is stored with the locale.  It will remain valid until a subsequent call to freelocale(3).  If a thread-local
     locale is in effect then the return value from localeconv() will remain valid until the locale is destroyed.

ERRORS

     No errors are defined.
