NAME

locale.h - category macros

SYNOPSIS

#include <locale.h>

DESCRIPTION

Some of the functionality described on this reference page extends the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of IEEE Std 1003.1-2001 defers to the ISO C standard.

The <locale.h> header shall provide a definition for lconv structure, which shall include at least the following members. (See the definitions of LC_MONETARY in LC_MONETARY and LC_NUMERIC .)

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

The <locale.h> header shall define NULL (as defined in <stddef.h> ) and at least the following as macros:

LC_ALL
LC_COLLATE
LC_CTYPE

LC_MESSAGES

LC_MONETARY
LC_NUMERIC
LC_TIME

which shall expand to distinct integer constant expressions, for use as the first argument to the setlocale() function.

Additional macro definitions, beginning with the characters LC_ and an uppercase letter, may also be given here.

The following shall be declared as functions and may also be defined as macros. Function prototypes shall be provided.

struct lconv *localeconv (void); char *setlocale(int, const char *);

The following sections are informative.

APPLICATION USAGE

None.

RATIONALE
