11 int iswctype(wint_t wc, wctype_t desc);
12
14 If wc is a wide character having the character property designated by
15 desc (or in other words: belongs to the character class designated by
16 desc), the iswctype() function returns nonzero. Otherwise, it returns
17 zero. If wc is WEOF, zero is returned.
18
19 desc must be a character property descriptor returned by the wctype(3)
20 function.
21
23 The iswctype() function returns nonzero if the wc has the designated
24 property. Otherwise, it returns 0.
