lconv

Defined in header <locale.h> 
struct lconv;
+

The struct lconv contains numeric and monetary formatting rules as defined by a C locale. Objects of this struct may be obtained with localeconv. The members of lconv are values of type char and of type char*. Each char* member except decimal_point may be pointing at a null character (that is, at an empty C-string). The members of type char are all non-negative numbers, any of which may be CHAR_MAX if the corresponding value is not available in the current C locale.

+

Member objects

Non-monetary numeric formatting parameters

+ + +
char* decimal_point
 the character used as the decimal point
(public member object)
char* thousands_sep

char n_cs_precedes
 1 if currency_symbol is placed before negative value, ​0​ if after
(public member object)

(public member object)
char n_sign_posn
 indicates the position of negative_sign in a negative monetary value
(public member object)

International monetary numeric formatting parameters

+ + + + + + + +
char* int_curr_symbol
 the string used as international currency name in the current C locale
(public member object)
char int_frac_digits
 the number of digits after the decimal point to display in an international monetary quantity
(public member object)
char int_p_cs_precedes
+
(C99)
 1 if int_curr_symbol is placed before non-negative international monetary value, ​0​ if after
(public member object)
char int_n_cs_precedes
+
(C99)
 1 if int_curr_symbol is placed before negative international monetary value, ​0​ if after
(public member object)
char int_p_sep_by_space
+
(C99)
 indicates the separation of int_curr_symbol, positive_sign, and the non-negative international monetary value
(public member object)
char int_n_sep_by_space
+
(C99)
 indicates the separation of int_curr_symbol, negative_sign, and the negative international monetary value
(public member object)
char int_p_sign_posn
+
(C99)
 indicates the position of positive_sign in a non-negative international monetary value
(public member object)
char int_n_sign_posn
+
(C99)
 indicates the position of negative_sign in a negative international monetary value
(public member object)


The characters of the C-strings pointed to by grouping and mon_grouping are interpreted according to their numeric values. When the terminating '\0' is encountered, the last value seen is assumed to repeat for the remainder of digits. If CHAR_MAX is encountered, no further digits are grouped. The typical grouping of three digits at a time is "\003".

+

The values of p_sep_by_space, n_sep_by_space, int_p_sep_by_space, int_n_sep_by_space are interpreted as follows:

+ + + +
0 no space separates the currency symbol and the value
1 sign sticks to the currency symbol, value is separated by a space
2 sign sticks to the value. Currency symbol is separated by a space

The values of p_sign_posn, n_sign_posn, int_p_sign_posn, int_n_sign_posn are interpreted as follows:

+ + + + + +
0 parentheses around the value and the currency symbol are used to represent the sign
1 sign before the value and the currency symbol
2 sign after the value and the currency symbol
3 sign before the currency symbol
4 sign after the currency symbol

Example

#include <locale.h>
+#include <stdio.h>
+ 
+int main(void)
+{
+    setlocale(LC_ALL, "ja_JP.UTF-8");
+    struct lconv *lc = localeconv();
+    printf("Japanese currency symbol: %s(%s)\n", lc->currency_symbol, lc->int_curr_symbol);
+}

Possible output:

+
Japanese currency symbol: ￥(JPY )
