NAME
langinfo.h, langinfo - language information constants SYNOPSIS
#include <langinfo.h> DESCRIPTION
The <langinfo.h> header contains the constants used to identify items of langinfo data (see nl_langinfo(3C)). The type of the constant, nl_item, is defined as described in <nl_types.h>. The following constants are defined. The entries under Category indicate in which setlocale(3C) category each item is defined. Constant Category Meaning CODESET LC_CTYPE codeset name D_T_FMT LC_TIME string for formatting date and time D_FMT LC_TIME date format string T_FMT LC_TIME time format string T_FMT_AMPM LC_TIME a.m. or p.m. time format string AM_STR LC_TIME ante-meridiem affix PM_STR LC_TIME post-meridiem affix DAY_1 LC_TIME name of the first day of the week (for example, Sunday) DAY_2 LC_TIME name of the second day of the week (for example, Monday) DAY_3 LC_TIME name of the third day of the week (for example, Tuesday) DAY_4 LC_TIME name of the fourth day of the week (for example, Wednesday) DAY_5 LC_TIME name of the fifth day of the week (for example, Thursday) DAY_6 LC_TIME name of the sixth day of the week (for example, Friday) DAY_7 LC_TIME name of the seventh day of the week (for example, Saturday) ABDAY_1 LC_TIME abbreviated name of the first day of the week ABDAY_2 LC_TIME abbreviated name of the second day of the week ABDAY_3 LC_TIME abbreviated name of the third day of the week ABDAY_4 LC_TIME abbreviated name of the fourth day of the week ABDAY_5 LC_TIME abbreviated name of the fifth day of the week ABDAY_6 LC_TIME abbreviated name of the seventh day of the week ABDAY_7 LC_TIME abbreviated name of the seventh day of the week MON_1 LC_TIME name of the first month of the year MON_2 LC_TIME name of the second month MON_3 LC_TIME name of the third month MON_4 LC_TIME name of the fourth month MON_5 LC_TIME name of the fifth month MON_6 LC_TIME name of the sixth month MON_7 LC_TIME name of the seventh month MON_8 LC_TIME name of the eighth month MON_9 LC_TIME name of the ninth month MON_10 LC_TIME name of the tenth month MON_11 LC_TIME name of the eleventh month MON_12 LC_TIME name of the twelfth month ABMON_1 LC_TIME abbreviated name of the first month ABMON_2 LC_TIME abbreviated name of the second month ABMON_3 LC_TIME abbreviated name of the third month ABMON_4 LC_TIME abbreviated name of the fourth month ABMON_5 LC_TIME abbreviated name of the fifth month ABMON_6 LC_TIME abbreviated name of the sixth month ABMON_7 LC_TIME abbreviated name of the seventh month ABMON_8 LC_TIME abbreviated name of the eighth month ABMON_9 LC_TIME abbreviated name of the ninth month ABMON_10 LC_TIME abbreviated name of the tenth month ABMON_11 LC_TIME abbreviated name of the eleventh month ABMON_12 LC_TIME abbreviated name of the twelfth month ERA LC_TIME era description segments ERA_D_FMT LC_TIME era date format string ERA_D_T_FMT LC_TIME era date and time format string ERA_T_FMT LC_TIME era time format string ALT_DIGITS LC_TIME alternative symbols for digits RADIXCHAR LC_NUMERIC radix character THOUSEP LC_NUMERIC separator for thousands YESEXPR LC_MESSAGES affirmative response expression NOEXPR LC_MESSAGES negative response expression YESSTR LC_MESSAGES affirmative response for yes/no queries NOSTR LC_MESSAGES negative response ro yes/no queries CRNCYSTR LC_MONETARY local currency symbol, preceded by '-' if the symbol sould appear before the value, '+' if the symbol should appear after the value, or '.' if the symbol should replace the radix character If the locale's values for p_cs_precedes and n_cs_precedes do not match, the value of nl_langinfo(CRNCYSTR) is unspecified. The <langinfo.h> header declares the following as a function: char *nl_langinfo(nl_item); Inclusion of <langinfo.h> header may also make visible all symbols from <nl_types.h>. USAGE
Wherever possible, users are advised to use functions compatible with those in the ISO C standard to access items of langinfo data. In par- ticular, the strftime(3C) function should be used to access date and time information defined in category LC_TIME. The localeconv(3C) func- tion should be used to access information corresponding to RADIXCHAR, THOUSEP, and CRNCYSTR. ATTRIBUTES
