<locale.h>(0P)                                      POSIX Programmer's Manual                                     <locale.h>(0P)



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 require-
       ments 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 *);
