int iswcntrl(wint_t wc)

DESCRIPTION

iswcntrl tests whether its argument wc is a control wide character.

RETURN VALUE

iswcntrl returns 0 if the wide character is not a control character, or a nonzero value if it is a control character. If the argument is WEOF, 0 is returned.

The effect of iswcntrl on a non-wide character argument other than WEOF is undefined. Do not assume that iswcntrl returns either a 0 or a 1.
