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.

indicates the separation of
currency_symbol
,
negative_sign
, and the negative monetary value
(public member object) |
|
char
p_sign_posn

indicates the position of
positive_sign
in a non-negative monetary value
(public member object) |
|
char
n_sign_posn

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 )
