#include <langinfo.h>
char *nl_langinfo(nl_item item);Retrieves from the current locale the string that describes the requested information specified by item.
For a list of macros that define the constants used to identify the information queried in the current locale, see Table 1.
If successful, nl_langinfo() returns a pointer to a NULL-terminated string containing information concerning the active language or cultural area. The active language or cultural area is determined by the most recent setlocale() call. The array pointed to by the returned value is modified by subsequent calls to the function. The array shall not be modified by the user's program.
If the item is not valid, nl_langinfo() returns a pointer to an empty string.
