LIBRARY

SYNOPSIS
#include <wctype.h>
int iswctype(wint_t wc, wctype_t desc);
DESCRIPTION
If wc is a wide character having the character property designated by
desc (or in other words: belongs to the character class designated by
desc), then the iswctype() function returns nonzero. Otherwise, it re-
turns zero. If wc is WEOF, zero is returned.
desc must be a character property descriptor returned by the wctype(3)
function.

property. Otherwise, it returns 0.
