Individual and additional elements of the locale categories can +be queried. +.PP +Examples for the locale elements that can be specified in \fIitem\fP +using the constants defined in <langinfo.h> are: + +.TP +.BR CODESET \ (LC_CTYPE) +Return a string with the name of the character encoding used in the +selected locale, such as "UTF-8", "ISO-8859-1", or "ANSI_X3.4-1968" +(better known as US-ASCII). This is the same string that you get with +"locale charmap". For a list of character encoding names, +try "locale \-m", cf.\& +.BR locale (1). + +.TP +.BR D_T_FMT \ (LC_TIME) +Return a string that can be used as a format string for +.BR strftime (3) +to represent time and date in a locale-specific way. + +.TP +.BR D_FMT \ (LC_TIME) +Return a string that can be used as a format string for +.BR strftime (3) +to represent a date in a locale-specific way. + +.TP +.BR T_FMT \ (LC_TIME) +Return a string that can be used as a format string for +.BR strftime (3) +to represent a time in a locale-specific way. + +.TP +.BR DAY_ "{1\(en7} (LC_TIME)" +Return name of the \fIn\fP-th day of the week. [Warning: this follows +the US convention DAY_1 = Sunday, not the international convention +(ISO 8601) that Monday is the first day of the week.] + +.TP +.BR ABDAY_ "{1\(en7} (LC_TIME)" +Return abbreviated name of the \fIn\fP-th day of the week. + +.TP +.BR MON_ "{1\(en12} (LC_TIME)" +Return name of the \fIn\fP-th month. + +.TP +.BR ABMON_ "{1\(en12} (LC_TIME)" +Return abbreviated name of the \fIn\fP-th month. + +.TP +.BR RADIXCHAR \ (LC_NUMERIC) +Return radix character (decimal dot, decimal comma, etc.). + +.TP +.BR THOUSEP \ (LC_NUMERIC) +Return separator character for thousands (groups of three digits). + +.TP +.BR YESEXPR \ (LC_MESSAGES) +Return a regular expression that can be used with the +.BR regex (3) +function to recognize a positive response to a yes/no question. + +.TP +.BR NOEXPR \ (LC_MESSAGES) +Return a regular expression that can be used with the +.BR regex (3) +function to recognize a negative response to a yes/no question. + +.TP +.BR CRNCYSTR \ (LC_MONETARY) +Return the currency symbol, preceded by "\-" if the symbol should +appear before the value, "+" if the symbol should appear after the +value, or "." if the symbol should replace the radix character. +.PP +The above list covers just some examples of items that can be +requested.
