lconv(FP)


lconv -- Internationalization (native language support) information

Syntax

#include <locale.h>

Description

The lconv structure contains the following members:

Member Default Description
decimal_point "." Decimal point
thousands_sep "" Thousands separator
grouping "" Size of groups of digits
int_curr_symbol "" International currency symbol
currency_symbol "" Currency symbol
mon_decimal_point "" Monetary decimal point
mon_thousands_sep "" Monetary thousands separator
mon_grouping "" Monetary groupings
positive_sign "" Positive sign
negative_sign "" Negative sign

int_frac_digits
frac_digits

CHAR_MAX
CHAR_MAX
Number of digits used to display the fractions of a monetary unit; for example, two digits are used for $1.99
p_cs_precedes CHAR_MAX Whether the currency_symbol precedes (1) or succeeds (0) a positive monetary value; for example, $99.97 or .99$
p_sep_by_space CHAR_MAX Whether a space separates a currency_symbol from a positive value; for example, $99.97 (value is 0) or $ 99.97 (value is 1)
n_cs_precedes CHAR_MAX Whether a currency_symbol precedes (1) or succeeds (0) a negative monetary value; for example, $-99.97 or -.99$
n_sep_by_space CHAR_MAX Whether a space separates a currency_symbol from a negative value; for example, $-99.97 (value is 0) or $ -99.97 (value is 1)
p_sign_posn CHAR_MAX How to designate a positive monetary value. If the value is 0, parentheses are used, for example, ($99.97). If the value is 1, then the value of positive_sign is used; if 2 the sign string succeeds the value, if 3, the sign string precedes the value and the currency_symbol; if 4, the sign string immediately succeeds the currency_symbol. For example, if positive_sign is set to ``+'', then the result is +$99.97.
n_sign_posn CHAR_MAX How to designate a negative monetary value. Uses the same values as p_sign_posn, except that the sign string is the negative_sign string.

 |                  |          | same values as p_sign_posn,   |
 |                  |          | except that the sign string   |

If a string member in the lconv structure has the value "" (the null string) or if a char member has the value CHAR_MAX, then the value for the member is is unavailable in the current locale.

CHAR_MAX is usually defined as decimal 127 unless the program is compiled with the -J compiler option. The -J option allows the user to treat char types as unsigned integers instead of signed integers. Thus, CHAR_MAX is changed in the header file <limits.h> to the value 255. However, the locale files were built with the assumption that CHAR_MAX equals 127. In this case you should use the value 127 explicitly instead of CHAR_MAX.


NOTE: Currently, the only locale values supported for C are the default values listed above. Different values may be supported by other languages; these may be obtained from the appropriate locale documentation.
