#include <locale.h>
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 *);
