iswprint - test for a printing wide-character code
int iswprint(wint_t wc);
The iswprint() function tests whether wc is a wide-character code representing a character of class print in the program's current locale, see the Locale specification.
In all cases wc is a wint_t, the value of which must be a wide-character code corresponding to a valid character in the current locale or must equal the value of the macro WEOF. If the argument has any other value, the behaviour is undefined.
The iswprint() function returns non-zero if wc is a printing wide-character code; otherwise it returns 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.
