localeconv - cppreference.com

struct lconv* localeconv(void);

The localeconv function obtains a pointer to a static object of type lconv, which represents numeric and monetary formatting rules of the current C locale.

[edit] Parameters

(none)

[edit] Return value

pointer to the current lconv object.

[edit] Notes

Modifying the object references through the returned pointer is undefined behavior.

localeconv modifies a static object, calling it from different threads without synchronization is undefined behavior.

[edit] Example

#include <locale.h>
#include <stdio.h>
 
int main(void)
{
    setlocale(LC_MONETARY, "en_IN.utf8");
    struct lconv* lc = localeconv();
    printf("Local Currency Symbol        : %s\n", lc->currency_symbol);
    printf("International Currency Symbol: %s\n", lc->int_curr_symbol);
}

Output:

Local Currency Symbol        : â¹
International Currency Symbol: INR
