Description:
The nl_langinfo() function returns a pointer to a static string containing information relevant to the particular language or cultural area defined in the current locale.
Note:
- Don't modify the returned string. The value of the string might be invalidated by subsequent calls to this function.
- QNX OS provides this function for POSIX compatibility, but it isn't adequate for internationalization. QNX OS ships the International Components for Unicode (ICU) libraries (libicu*) that you can use instead. For more information about ICU, see https://icu.unicode.org/home.
Returns:
A pointer to the requested string, or an empty string if the item couldn't be found.
