NAME

langinfo − language information constants

SYNOPSIS

#include <langinfo.h>

DESCRIPTION

This header file contains the constants used to identify items of langinfo data (see nl_langinfo(3C)). The mode of items is given in <nl_types.h>. The following constants are defined ( CATEGORY indicates in which setlocale(3C) category each item is defined):

Constant	Category	Description
D_T_FMT	LC_TIME	String for formatting the %c (date and time) directive of date(1), getdate(3C), and strftime(3C).
D_FMT	LC_TIME	String for formatting the %x (date) directive of date(1), getdate(3C), and strftime(3C).
T_FMT	LC_TIME	String for formatting the %X (time) directive of date(1), getdate(3C), and strftime(3C).
DAY_1	LC_TIME	Name of the first day of the week (“Sunday” in English). :::
DAY_7	LC_TIME	Name of the seventh day of the week.
ABDAY_1	LC_TIME	Abbreviated name of the first day of the week (“Sun” in English).
ABDAY_7	LC_TIME	Abbreviated name of the seventh day of the week.
MON_1	LC_TIME	Name of the first month in the Gregorian year. :::
MON_12	LC_TIME	Name of the twelfth month.
ABMON_1	LC_TIME	Abbreviated name of the first month. :::
ABMON_12	LC_TIME	Abbreviated name of the twelfth month.
RADIXCHAR	LC_NUMERIC	Radix character (“decimal point” in English). The string returned is the same as the decimal_point element in the structure returned by localeconv(3C).
THOUSEP	LC_NUMERIC	Separator for thousands. The string returned is the same as the thousands_sep element in the structure returned by localeconv(3C).
YESEXPR	LC_MESSAGES	Affirmative response for expression.
NOEXPR	LC_MESSAGES	Negative response for expression.
YESSTR	LC_MESSAGES	Affirmative response for yes/no questions. (Obsolete: use YESEXPR)
NOSTR	LC_MESSAGES	Negative response for yes/no questions. (Obsolete: use NOEXPR)
CRNCYSTR	LC_MONETARY	Symbol for currency preceded by “−” if it precedes the number, “+” if it follows the number, and “.” if it replaces the radix. For example, “−DM” would be used for German (DM1234,56), “+ Kr” for Danish (1234,56 Kr), and “.$” for Portuguese (1234$56). See localeconv(3C) for alternative currency formatting information.
BYTES_CHAR	LC_CTYPE	Maximum number of bytes per character for the character set used for the specified language. For example, “1” for English and most European languages, and “2” for Japanese and several other Asian languages. This constant is an HP proprietary item and may not be portable to other platforms.
DIRECTION	LC_ALL	Value to indicate text direction. Values currently defined include “null”, “0” and “1”. Values of “null” or “0” indicate that characters are arranged from left-to-right within a line and lines are arranged from top-to-bottom. A value of “1” indicates that characters are arranged from right-to-left within a line and lines are arranged from top-to-bottom. This constant is an HP proprietary item and may not be portable to other platforms.
ALT_DIGIT	LC_NUMERIC	A string of the characters that are mapped into the ASCII equivalent string “0123456789b+-.,eE” (where b is a blank). This is also the reverse mapping for output. It is not assumed that the character code values of digits are contiguous or that they are one byte values. A null value for the string indicates that the language has no alternative digits. This constant is an HP proprietary item and may not be portable to other platforms.
ALT_PUNCT	LC_CTYPE	A string of the characters that are mapped into the ASCII equivalent string “b!"#$%&’()∗+,−./:;<=>?@[\]^_‘{\|}~” (where b is a blank) in American usage. This is also the reverse mapping for output. It is not assumed that the character code values of punctuation characters are contiguous or that they are one byte values. If any punctuation characters do not have equivalent alternatives, ASCII codes are used in the alternative punctuation string. A null value for the string indicates that the language has no alternative punctuation characters. This constant is an HP proprietary item and may not be portable to other platforms.
AM_STR	LC_TIME	Ante meridiem string used with 12-hour time formats ("AM" in English)
PM_STR	LC_TIME	Post meridiem string used with 12-hour time formats ("PM" in English)
YEAR_UNIT	LC_TIME	Symbol for year. This is usually required to specify date for Asian languages.
MON_UNIT	LC_TIME	Symbol for month.
DAY_UNIT	LC_TIME	Symbol for day.
HOUR_UNIT	LC_TIME	Symbol for hour. This is usually required to specify time for Asian languages.
MIN_UNIT	LC_TIME	Symbol for minute.
SEC_UNIT	LC_TIME	Symbol for second.
ERA_D_FMT	LC_TIME	Default string for formatting the %E (Emperor/Era name and year) directive of date(1) and strftime(3C) if an individual era format is not specified for an era (see localedef(1M)).
T_FMT_AMPM	LC_TIME	Time representation in the 12-hour clock format with AM_STR and PM_STR.

WARNINGS

It is recommended to use strftime() to access date and time information defined in category (see strftime(3C)), LC_TIME and localeconv(3C) to access information corresponding to RADIXCHAR, THOUSEP, and CRNCYSTR (see localeconv(3C)).
