.TH locale.h 3 .SH NAME locale.h - category macros .SH SYNOPSIS #include <locale.h> The locale.h header declares the following functions: .nf char *setlocale(int category, const char *locale); struct lconv *localeconv(void); .fi .SH DESCRIPTION The locale.h header defines the following macros: .nf LC_ALL LC_COLLATE LC_CTYPE LC_MESSAGES LC_MONETARY LC_NUMERIC LC_TIME .fi These macros expand to integer constant expressions with distinct values, suitable for use as the first argument, .IR category , to the .B setlocale function. The locale.h header declares the lconv structure defined as follows: .nf char *currency_symbol char *decimal_point char frac_digits char *grouping char *int_curr_symbol char int_frac_digits char int_n_cs_precedes char int_n_sep_by_space char int_n_sign_posn char int_p_cs_precedes char int_p_sep_by_space char int_p_sign_posn char *mon_decimal_point char *mon_grouping char *mon_thousands_sep char *negative_sign char n_cs_precedes char n_sep_by_space char n_sign_posn char *positive_sign char p_cs_precedes char p_sep_by_space char p_sign_posn char *thousands_sep .fi The members of the .I lconv structure are: .TP 10 currency_symbol The local currency symbol applicable to the current locale. .TP decimal_point The decimal-point character used to format monetary quantities. .TP thousands_sep The character used to separate groups of digits before the decimal-point character in formatted monetary quantities. .TP grouping A string whose elements indicate the size of each group of digits in formatted nonmonetary quantities. .TP mon_decimal_point The decimal-point used to format monetary quantities. .TP mon_thousands_sep The separator for groups of digits before the decimal-point in formatted monetary quantities. .TP mon_grouping A string whose elements indicate the size of each group of digits in formatted monetary quantities. .TP positive_sign The string used to indicate a nonnegative-valued formatted monetary quantity. .TP negative_sign The string used to indicate a negative-valued formatted monetary quantity. .TP frac_digits The number of fractional digits (those after the decimal-point) to be displayed in a locally formatted monetary quantity. .TP p_cs_precedes Set to 1 or 0 if the currency_symbol respectively precedes or succeeds the value for a nonnegative locally formatted monetary quantity. .TP n_cs_precedes Set to 1 or 0 if the currency_symbol respectively precedes or succeeds the value for a negative locally formatted monetary quantity .TP p_sep_by_space Set to a value indicating the separation of the currency_symbol, the sign string, and the value for a nonnegative locally formatted monetary quantity. .TP n_sep_by_space Set to a value indicating the separation of the currency_symbol, the sign string, and the value for a negative locally formatted monetary quantity. .TP p_sign_posn Set to a value indicating the positioning of the positive_sign for a nonnegative locally formatted monetary quantity. .TP n_sign_posn Set to a value indicating the positioning of the negative_sign for a negative locally formatted monetary quantity. .TP int_curr_symbol The international currency symbol applicable to the current locale. .TP int_frac_digits The number of fractional digits (those after the decimal-point) to be displayed in an internationally formatted monetary quantity. .TP int_p_cs_precedes Set to 1 or 0 if the int_curr_symbol respectively precedes or succeeds the value for a nonnegative internationally formatted monetary quantity. .TP int_n_cs_precedes Set to 1 or 0 if the int_curr_symbol respectively precedes or succeeds the value for a negative internationally formatted monetary quantity. .TP int_p_sep_by_space Set to a value indicating the separation of the int_curr_symbol, the sign string, and the value for a nonnegative internationally formatted monetary quantity. .TP int_n_sep_by_space Set to a value indicating the separation of the int_curr_symbol, the sign string, and the value for a negative internationally formatted monetary quantity. .TP int_p_sign_posn Set to a value indicating the positioning of the positive_sign for a nonnegative internationally formatted monetary quantity. .TP int_n_sign_posn Set to a value indicating the positioning of the negative_sign for a negative internationally formatted monetary quantity. .SH STANDARDS ISO/IEC 9899:1999 Section 7.11 ISO/IEC 9899:1999 Section 7.11.2.1 .SH SEE ALSO .BR localeconv (3) .BR setlocale (3)
