SYNOPSIS

#include <wctype.h>

int iswctype(wint_t wc, wctype_t desc)

DESCRIPTION

iswctype tests a wide character value wc for a property constructed by the wctype function. The return value indicates whether the wide character has the property specified by the desc argument.

RETURN VALUE

iswctype returns 0 if the wide character does not have the property of the value supplied by desc, or a nonzero value if it does have that property. If the supplied property is invalid, iswctype returns 0. If the argument is WEOF, 0 is returned.

CAUTION

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