int iswprint(wint_t wc);
The iswprint() function shall test whether wc is a wide-character code representing a character of class print in the program's current locale; see the Base Definitions volume of IEEE Std 1003.1-2001, Chapter 7, Locale.
The wc argument is a wint_t, the value of which the application shall ensure is a wide-character code corresponding to a valid character in the current locale, or equal to the value of the macro WEOF. If the argument has any other value, the behavior is undefined.
The iswprint() function shall return non-zero if wc is a printable wide-character code; otherwise, it shall return 0.
No errors are defined.

To ensure applications portability, especially across natural languages, only this function and those listed in the SEE ALSO section should be used for classification of wide-character codes.
