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 pro-
vided.
struct lconv *localeconv (void);
char *setlocale(int, const char *);
The following sections are informative.
APPLICATION USAGE
