#include <locale.h>
struct lconv *localeconv(void);Sets the components of a structure having type struct lconv to values appropriate for the current locale. The structure may be overwritten by another call to localeconv() or by calling setlocale() and passing LC_ALL, LC_MONETARY, or LC_NUMERIC.
For a list of the elements in the lconv structure, see Table 1.
Pointers to strings with a value of "" indicate that the value is not available in the C locale or is of 0 length. char types with a value of UCHAR_MAX indicate that the value is not available in the current locale.
Returns a pointer to the structure.
