Standard C Library Functions localeconv(3C)
NAME
localeconv - get numeric formatting information
SYNOPSIS
#include
struct lconv *localeconv(void);
DESCRIPTION
The localeconv() function sets the components of an object
with type struct lconv (defined in) with the values appropriate for the formatting of numeric quantities (monetary and otherwise) according to the rules of the current locale (see setlocale(3C)). The definition of struct lconv is given below (the values for the fields in the "C" locale are given in comments). char *decimal_point; /* "." */
char *thousands_sep; /* "" (zero length string) */
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_MAX */
char frac_digits; /* CHAR_MAX */
char p_cs_precedes; /* CHAR_MAX */
char p_sep_by_space; /* CHAR_MAX */
char n_cs_precedes; /* CHAR_MAX */
char n_sep_by_space; /* CHAR_MAX */
char p_sign_posn; /* CHAR_MAX*/
char n_sign_posn; /* CHAR_MAX */
The following members are also available to SUSv3-conforming
applications. See standards(5)char int_p_cs_precedes; /* CHAR_MAX */

The members of the structure with type char * are strings,any of which (except decimal_point) can point to a null
string (""), to indicate that the value is not available in the current locale or is of zero length. The members withtype char are non-negative numbers, any of which can be

applicable to the current locale.The first three characters con-
tain the alphabetic international currency symbol in accordance with those specified in the ISO 4217: 1995 standard. The fourth character (immediately preceding the null byte) is the characterused to separate the interna-
tional currency symbol from the monetary quantity.char *currency_symbol The local currency symbol appli-
cable to the current locale.char *mon_decimal_point The decimal point used to format

positioning of the negative_sign
for a negative internationally formatted monetary quantity.The elements of grouping and mon_grouping are interpreted
according to the following:{CHAR_MAX} No further grouping is to be performed.
0 The previous element is to be repeatedly used for the remainder of the digits. other The integer value is the number of digits that comprise the current group. The next element is examined to determine the size of the next group of digits before the current group.The values of p_sep_by_space, n_sep_by_space,
int_p_sep_by_space, and int_n_sep_by_space are interpreted
according to the following: 0 No space separates the currency symbol and value. 1 If the currency symbol and sign string are adjacent, a space separates them from the value; otherwise, a space separates the currency symbol from the value. 2 If the currency symbol and sign string are adjacent, a space separates them; otherwise, a space separates theSunOS 5.11 Last change: 12 Dec 2003 5

sign string from the value.In an SUSv3-conforming application, for int_p_sep_by_space
and int_n_sep_by_space, the fourth character of
int_curr_symbol is used instead of a space.
The values of p_sign_posn, n_sign_posn, int_p_sign_posn, and
int_n_sign_posn are interpreted according to the following:
0 Parentheses surround the quantity and currency_symbol
or int_curr_symbol.
1 The sign string precedes the quantity andcurrency_symbol or int_curr_symbol.
2 The sign string succeeds the quantity andcurrency_symbol or int_curr_symbol.
3 The sign string immediately precedes thecurrency_symbol or int_curr_symbol.
4 The sign string immediately succeeds thecurrency_symbol or int_curr_symbol.
RETURN VALUES
The localeconv() function returns a pointer to the filled-in
object. The structure pointed to by the return value may beoverwritten by a subsequent call to localeconv().
