C Standard Library - <locale.h>

Description

The C library function struct lconv *localeconv(void) sets or reads locale-specific information. It returns an object of type lconv structure.

Declaration

Here is the declaration for the localeconv() function.

struct lconv *localeconv(void)

Parameters

Return Value

The function returns a pointer to the current locale's struct lconv, which has the following structure:

typedef struct {
   char *decimal_point;
   char *thousands_sep;
   char *grouping;    
   char *int_curr_symbol;
   char *currency_symbol;
   char *mon_decimal_point;
   char *mon_thousands_sep;
   char *mon_grouping;
   char *positive_sign;
   char *negative_sign;
   char int_frac_digits;
   char frac_digits;
   char p_cs_precedes;
   char p_sep_by_space;
   char n_cs_precedes;
   char n_sep_by_space;
   char p_sign_posn;
   char n_sign_posn;
} lconv;

Example

The following example demonstrates the use of the localeconv() function.

#include <locale.h>
#include <stdio.h>

int main ()
{
   struct lconv * lc;

   setlocale(LC_MONETARY, "it_IT");
   lc = localeconv();
   printf("Local Currency Symbol: %s\n",lc->currency_symbol);
   printf("International Currency Symbol: %s\n",lc->int_curr_symbol);

   setlocale(LC_MONETARY, "en_US");
   lc = localeconv();
   printf("Local Currency Symbol: %s\n",lc->currency_symbol);
   printf("International Currency Symbol: %s\n",lc->int_curr_symbol);

   setlocale(LC_MONETARY, "en_GB");
   lc = localeconv();
   printf("Local Currency Symbol: %s\n",lc->currency_symbol);
   printf("International Currency Symbol: %s\n",lc->int_curr_symbol);

   printf("Decimal Point = %s\n", lc->decimal_point);

   return 0;
}

Let's compile and run the above program, which will produce the following result:

Local Currency Symbol: EUR
International Currency Symbol: EUR
Local Currency Symbol: $
International Currency Symbol: USD
Local Currency Symbol: £
International Currency Symbol: GBP
Decimal Point = .
