NAME
       iswctype - wide character classification

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), the iswctype function returns non-zero. Otherwise it returns zero. If wc is WEOF, zero is returned.

       desc must be a character property descriptor returned by the wctype function.

RETURN VALUE
       The iswctype function returns non-zero if the wc has the designated property. Otherwise it returns 0.
