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 defini-
       tions 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 *);
